I have the att m8 which I converted fully to gpe...can't go back to sense till ruu's become available later if I wanted to...anyway the reason international Roms work is because the att version is pretty much the same hardware as international/gpe... Any ROM from the international side will work... Before I did the ruu gpe conversion...I ran viper arhd insert coin virtuous renovate on my att m8 with no issues.
As you are s-off, could you not update your cid and firmware? Then you are free to flash any rom.
I'm not really clued up on carrier branded phones through so I could be mistaken.

I was wondering if modem or any driver component meant for specific version of hardware is included in Rom, and I flash it over to AT&T version, then will it not be a problem? But I think it really not is an issue.
CID/MID has nothing to do with roms, the only time this comes into play is if you are trying to OTA or RUU back to stock, RUU and OTA check the CID/MID and determine whether or not the model is compatible with that particular OTA/RUU... As for modems, generally roms do not include radios/basebands, most roms are just system/boot, if a radio is included it is more then likely stated in the Devs OP, also with S-Off its easy enough to fix radio issues should you run into this. As I said the ATT variant is based off the international and gpe variant hence any rom will work.
