Mega Man Villains Idea

I was watching a playthrough of Mega Man: Maverick Hunter X (a PSP remake of Mega Man X) and I noticed that Boomer Kuwanger changes his attack pattern when you use the Homing Missile compared to the Mega Buster (I always used Homing Missiles against him so I never knew he had a different attack pattern).

How about a Mega Man game where each robot master is susceptible to two other masters' weapons. One weapon causes more damage while the other weapon alters the attack pattern to make it easier to defeat. If you then make each robot master's attack pattern difficult to dodge, players have an incentive to use either weapon (more damage to kill it quicker or easier attack pattern to survive longer).
