Non-carrier M7 Roms on AT&T M7

Will the ROM's found in the non-carrier forums for the M7 work on the AT&T M7?

I see there's a few MM ROMS, as well as some AOSP ROM's (CM13, AICP)

I'm curious if these will work on the AT&T M7. I just ordered a great condition blue One on eBay and i'm wondering what I can do with it.
