No idea, but the Bushman looks like it requires an SRM-6 in the head to match the art, which would not fit until Clantech or small cockpits came along later.
The Nicholiev should be workable. Dual peepers or AC/10s in the right torso (ammo elsewhere), trio of medium or small lasers in each “arm”, and an SRM-6 in each leg. It’s like a Battlemaster that did the Banshee-s conversion to a 3/5 engine and went through a washing machine.
The Mackarel is obviously an underwater design and would have to wait for torpedos, UMUs, etc. to match its art.
