Not going to happen. Take a look around at this community and you'll notice that swahili net and wooden calculators is what keeps it together, both things not compatible at all with GTA V.
If you or your team are able to set it up and get it running we can get that branch an area within the community forum, but, speaking for the SA-MP management chapter, we won't delegate development ressources (or any other further ressources for that matter) to it. The last two attempts to officially branch out to other games were closed for inactivity in quite few time.
