Default [Q] Carrier specific ROMs

So I found this Google Play Edition ROM port from the M8 (http://forum.xda-developers.com/show....php?t=2531235) and unfortunately it is specific to the Verizon(CDMA) carrier and I was wondering if there was a way to port it to AT&T(GSM). I already tried the APN editing and it did not work. Any help would be greatly appreciated.

Thanks in advance.
