Q is for Question Time - Rack Toy Question

Sean at Fantasy Toy Soldiers had these somewhere, and I think he has more poses than me, but he too was asking for further information, so, hoping there are different readers here, I'll ask too - does anyone know anything about these chaps and chapesses?

They are about 50mm (a Hing Fat trait?) and pretty mid-to-late 1980's in style; a bit Star Wars, a bit Nottingham Mafia, a bit post-apocalyptic and straight-to-video! Medium density polyethylene and, apart from the sci-fi subject, typical 'army men' rack toy fodder.

Colours are also very Hing Fat, ignoring the two shades of grey, and these are also very reminiscent of the Galaxy Rangers from Hing Fat, which is not to say they are Hing Fat, but might be, or might have been supplied by them for someone else?

 

Looking at the two in the larger picture, could they be meant to be Buck and Wilma from Buck Rogers, after the 80's TV series? They carry no mark (which is also the case with the Galaxy Rangers I think?), and I have one heat-shrinkage figure who is useable - the white plastic chap in the small picture.
