There is a long list of reasons NOT to house them together, some of which have already been mentioned.

As far as a good reason TO house them together? There isn't one.

Since you already have two enclosures, do yourself and your snakes a favor, and keep them separate, like a responsible keeper does.

Sure there are people who keep snakes together all the time, sure they may successfully do so for many years. The question you need to ask yourself is this...Is the very real risk worth the tiny little gain? To me the answer is no.
