This isn't really a suggestion, it's asking for knowledge on the inner workings of the game to better make suggestions.
These Questions being, in detail:
Is it possible for a feat to have stat OR-Requirements, as in, require stat X or stat Y? I've seen skills, so I guess yes, but you never know.
Is it possible to have a special skill work X times per round before a cooldown starts, without the awkward workaround of giving the character the same ability twice?
Edit: Can a Feat have a requirement like "2 Attributes on 9 or higher"? No matter which?
Examples:
I recently shelved a character that was based around the concept of excessive suppressive fire, but two bursts aren't possible. So I figured, a feat
"Controlled Bursts" that reduced the number of Bullets by one but granted +1 bursts a round would be neat, possibly with a precision bonus. I wouldn't suggest it, though, because I have no idea if it's even feasible. Obviously, "Controlled Burst" could be a new ability requiring Spec Ops, and thus it wouldn't be a problem, but for Science!
As another option for the thread "More options for the Intelligent Combatant?" I figured it'd be nice to have a special melee attack that ignored half the damage resistance of an opponent, and that could be fluffed either as an Intelligence skill (Deducting a weakpoint) or a Will skill (Psychokinetics).
