Proper husbandry won't fix all of the problems. There will still be the issue of the snakes stressing each other out. In the wild, these snakes would not come in such close contact with each other (unless it was breeding season). And feeding time will also be a lot harder. You will have to feed each snake separately. This can become difficult with larger snakes and when you open that cage, its bad enough to have one large, hungry snake ready to eat, imagine two!

In the end, you are going to do what you want to do, but I'm just giving you my opinion.
