Mongoose
I think this would be a great fit for Mongoose, or more specifically Flaming Cobra. For those who don't know, Golden Heroes was a superhero rpg published by Games Workshop in 1984. It had an innovative character creation system and a combat system that reflected the panels of a comic book page. It was supported for a while in White Dwarf and there were a couple of scenarios published, which uniquely in the super rpg market were britain-centric. The game drifted into semi-obscurity for a long time although was fondly remembered by many (including me). Then, in 2006, one of the games authors Simon Burley relaunched the game as a pdf product called Squadron UK. This was a slightly revised version of the game and has been followed by several adventures and sourcebooks. I read recently on the game's yahoo group that Simon is considering reworking the game and rebranding it somewhat which would make a great opportunity for the game to get some wider attention. With Mongoose publishing that other great british rpg, Dragon Warriors, I think Golden Heroes would be right at home and it would be great to see it in a new, full colour version.
