Would not recommend it. If they were to encounter each other in the wild it would be a different story but keeping them enclosed together 24/7 is definitely going to give you issues in the long run.

-Who knows what the different species might do to one another?
-Different husbandry needs
-Disease/Parasites

I'm sure there are plenty of other reasons, it's just not a good idea.
