Should I breed if the male is significantly bigger?

I have a tendency to ramble, so I'll put a TLDR at the end.
I've had this female AZ blonde for over a year. I know that she molted within the last 6 months because when I first got her she was missing a leg and I know that sometime after I moved into my new apartment she molted bc she has all of her legs again. I haven't lived here for 6 months yet so Ik she hasn't past the point when breeding is not recommended. She's ~3-4 inches. I suspect she's still young since she hasn't reached her full size however I have seen that she is fully mature. I sexed her and she has the flap. Being that I live in AZ myself, I'll go hunting for any wandering males. I came across a male once that I caught however he was absolutely massive. To the point where he was 3-4 TIMES the size of her (He was so massive that not only did he surpass the size of the average female to the point where I doubted he could be a male until I saw his VERY prominent tibial hooks, but he was about 7 inches). I decided not to attempt breeding since she was missing a leg, I got her only a few months ago, and I didn't know when she last molted.
Well today we found another male. He's much smaller than the other one, however he is about 4-5 inches. Not including the leg span, his body is almost twice the size of her body. So I'm hesitant on whether to breed.

TLDR:
The wild male I caught is about twice the size of my female (I'm looking at the size of the body not the legspan) and I really want to breed them, however I don't know whether I should. My female is roughly 3-4 inches and is fully mature. She has molted within the last 6 months and is pretty docile. She's never threat postured and is fairly chill. I just got this male less than an hour ago and he's been very chill. He doesn't seem skittish or shy, but definitely not aggressive in the least. No trouble at all housing him into a temp enclosure. Based on this information, I'm conflicted on whether to breed them. Is it risky to attempt breeding when the male is bigger than the female, despite their docile nature? Ik that he's itching to mate bc he won't stop pacing and I figure that he could sense she's a female. But I worry that her size might either make him think about dinner, or make her think that he's a threat and would try to run away. I couldn't find any info online about the pros and/or cons of breeding with a bigger male. Any experienced breeders out there with advice? Or anyone have a story of their experience with this scenario?

Additional Info:
I've owned tarantulas for over 2 years now. I make sure to research thoroughly and I'm familiar with the breeding process but have never actually bred myself. (My male pink toe passed away before I could breed him because I wasn't sure if he had made a sperm web or not). I really want to take the next step in this hobby, but I also really want to be safe and responsible. I don't plan on breeding them asap since I want the male to settle in first, but I also don't want to miss this opportunity again. Any information as soon as possible would be greatly appreciated!

i would first be sure youve got Arizona blondes and not some other species. Because they really should not be getting that large to start with.

If shes 4 inches, she should be good to breed. however id really reccomend posting photos of both her and the two males to make sure that things are good. use a size reference, the same one, between all 3 photos if possible.

You've seen that the female's spermathecae are fully sclerotized on the most recent exuvia? As long as that is the case, she should be good to go. As with any pairing, you'll need to be watching closely and be ready to intervene if either M or F get aggressive or defensive...

Thank you for the feedback. You don't think the male's size should be an issue?

Well the first male died way long time ago. Ik that these males are genuine Arizona Blondes because we do not have any other tarantula species native to my area. I'm in the middle of the arizona desert, about 5 hours north of the border. In terms of looks they fit the AZ blonde description. (Ik that this isn't the most accurate way to tell but it's at least another sign). I will post pictures in a second. Hopefully the female wont try to hide.

Sorry about the low image quality. I hope these will do to help with scaling. The female is in the bigger enclosure. Keep in mind I'm estimating these sizes to the best of my ability. And yes, I need to feed my female soon. She is looking quite malnourished.

Says youve got at least a dozen species native to arizona... Especially in the genus Aphonopelma. I would say chances are good you need to have them identified properly before any breeding. I am really only an "expert" in identifying true spiders unfortunately. I would ask an expert to help you out with that.

That'll be up to her, I suppose. I can't imagine that pairings in the wild only occur with males and females of equal size or when the female is larger. That said, your female needs significant conditioning prior to any pairing attempts. It'll take more than a meal or 2 - probably at least a couple months of heavy feeding.

I'll probably take it to the Sonoran desert museum. I know they have tarantulas there and I've talked with a few of the experts there. Maybe they can help identify him. In terms of the area I live in, we don't have any of the other species around here, tho I could be wrong so I'll be sure to have an expert identify him. Definitely wouldn't want to be selling a hybrid under false claim.
