I don't think I would, no. Nothing against them, but it just seems like it would cause conflicts. I don't think my spiritual/religious views (or lack thereof) have to completely align with someone else's, so I think I'd be okay with an agnostic, a deist, or anyone along those lines, but I just don't feel my atheism and someone else's theism would mix too well. Especially if they were particularly devout.
On the other hand, it's still sort of a case by case basis, even with other atheists. My ex was much more of an anti-theist than I am, and that didn't mesh too well, either.
