I'm not sure how I stole his idea at all. If anything, it's not an original idea to begin with. Over-the-top mods with a plethora of powerful abilities are a common theme in mods. Ie. something like instagib mutators or super powerups in UT99. I pride myself on quality bottom-up execution though, which is something I felt that the two aforementioned mods lacked (although sani mod got much better with general tor, the ufo and biker curly; he should've kept working on it).
Most of my ideas -- past the original 7 INS clan members (plus z4 giraffe, who is the honorary pet member) -- were based around fighting game concepts (dhalsim, honda, doom), general class roles (stealth, assault, speed, defense, support, etc), and existing characters from other franchises (dante, richter, marine).
