Sometimes animals can interbreed if the species is very close to each other in the Genus. However, probably never happen as scorpions are predatory as well as cannibalistic. There has been several papers on species having two types of venom (in fact one researcher cautioned on handling the Desert Hairy due to his research showing that it had two types of venom). Here is the thing with any venomous animal, you may or may not respond to a "only hurts like a bee sting", but no one knows when that will happen to them. Several years ago a friend of mine was stung by a Bold Face Hornet (actually the largest of the Yellow Jacket family and not a wasp at all) - life flighted to save his life. Treat everything with respect, not because you could die but because they deserve it.
