Can Limax hybridise (and other slug questions)

For context, i do not have any member of the Limax genus (yet) but i wish to own some individuals in the future, of multiple species. Furthermore i do not want to attempt hybridisation of similar species both for the focus of keeping a genetically pure population (that could potentially be returned to the wild eventually) and for the risks it gives to the individuals.

Certain species of slugs do hybridise in the wild. A. lusitanicus hybridizes with A. rufus extremely rarely for example. Furthermore these young seem fertile too since their is a gradient of A.lusitanicus that show rufus like morphology. Presuming that i house species like Limax maximus, Limax dacampi or Limax cinereoniger (i would house Limax flavus together but i have seen them be predated on bye other species of slugs and the common consensus is they are probably a new genus) together would i be risking reproduction. Can these species form fertile hybrids? This is of particular concern because if i need to release them or cannot care for them, how can i release a hybrid (of either two native species , or one foreign and native). Furthermore failed copulations can lead to the death of individuals .

For reference Limax maximus is the leopard slug (native to my local area)
Limax cinereoniger is the largest type of slug in the world (native to my local area)
Limax dacampi is an Italian type of slug of considerable size. (non native, potential species complex)
