Post [Q] is it possible to instal at&t based roms on my verizon sch-i545?

my current set-up is surges deoxed nc5 rooted firmware. I have installed hyper-drive 16.1 and liked it but I would like to play around with more rom choices. is there a way to port at&t custom roms to work on my verizon galaxy s4? I can't find a good write-up on it, or tutorial and though googlie has done a great deal for the development community I just don't understand his xstrasmall patch or really understand auto port patches altogether. I would prefer installation methods to be by safestrap, as it is all I'm familiar with. Thank you, for your reply.
