Just making sure... you never want to put more than one snake in there at a time. If you mean you want to the setup to be versatile enough for any species of your choosing, but only one at a time, then that is a great idea. But you never, EVER want to house multiple snakes together.
You probably already know that, so I'm sorry if I am just giving you "no duh" information. There was a thread on here recently though where an individual was housing pythons and boas together.
Best of luck!
