Jumping spider and baby millipede

[Willow]

I have a bold jumper and was wondering if I could house her and my baby millipede together or if she would kill him.
I might just wait until Sam(millipede) gets too big for chewy(aka chewbaca)(jumper)
To attack

Sam is about the size of the crickets chewy eat except hes longer

Not a good idea, cohabing is very complicated and is usually just not a good idea, hard to say what might happen.
