Well, we already have upcoming Black Shark 3, MiG-19P with an RWR system that has never been on that exact model at all, the recent Harrier loadout shenanigans, FrankenJeff block 1 with a block 2 refueling boom (and maybe block 3 HMCS in the future, who knows) and the KH-66 that our Bis model never had, so an option in the mission editor to mount Lazur or Polyot is not all that much to ask for. Another matter entirely is that Lazur would have no use currently because DCS has no GCI vectoring, like, at all, only AWACS bull calls. That may change when we have dynamic campaign mechanics, corresponding mission generators and (hopefully) an AI real-time ground control system for Lazur to use. Until then there's simply no way to implement it.
