ATB housing?

[Zoe]

I'm looking into possibly getting a pair of ATBs in the not-so-distant future, but I had a quick question.
I would, ultimately, be housing them seperate. But for a few months after quaratine I will probably have to keep them together. If I needed to, would any problems arrise? Assuming the cage is of adequate size, there is enough heat, water, feeding is seperate etc.

Thanks!
