Default Will this ROM work for our phones? If not, what does it take to use it?

So I have noticed a lot of threads here share the GEE/GEEB label and we work closely with other versions of the Optimus G.

What I wanna know is if this ROM is safe to use on our phones, and if not, how can I sorta port it to work. This is one of the few ROMs I like more than mahdi or CM, and wanna try for a bit. (maybe add to the multi boot list?)

Please help! Thank you in advance!
