What year was Lowlight? I'm thinking Hasbro could knockout an incredible LL right now...
I'd add to your list a little I think Paul, if I were into the line... Probably not too much. Your ideas covered a lot of the best designs. Big Ben was almost a necessary guy, I mean being a brit commando and all... Brit's deserved a commando figure.
They've got a ton left yet pre-88 though... Airborne, Ripcord... Lots of pack-in figures too like Cutter, Deep Six, etc. Hell, there's no Zap yet.
