i think it'd be neat if you got a roll of 11, that roll wouldn't count toward the maximum number of rolls for that cor. so say you get one roll of 11, as long as you dont try to double-up again, you can have 3 rolls active at once. two 11s would be 4 active rolls. maybe with a hard cap of 3 or 4 rolls for game balance, but otherwise, in theory, you could have the effects of all your rolls at once as long as you keep getting 11s.
