Yeah, that sounds neat, although I'm not sure how it'd work for bow-users.
Well that depends. A ranged attack isn't something that would trigger a counterattack even if you are equipped with a ranged weapon. BUT, there was a system my GM came up with for pen and paper that stated if someone came within striking distance of an archer AND said archer had a melee weapon, they would be allowed a counterattack but at a reduced chance and reduced damage. So there is that.
