We kind of side-tracked your thread here, Kyle. Sorry about that!
Back to the point, no problem with housing multiple species if their size and requirements are the same. But no real benefit from the snakes' point of view.
I guess it's a matter of personal choice. I keep all my species separate, but for no specific reason. I'm sure other people house all females of mixed species and all males of mixed species together. Whatever works for you, I guess.
