Blitz2, Swdtech2, Morph2, etc...

Since you don't need to display names for SwdTech and Blitz, there should only be two major places where you would check which character is active and branch. The first is whatever byte controls how many skills the character knows; you'd need a second one for your second skill. The second is what skill is selected; you'd just start with a different offset for the different move set. Blitz has an additional hitch for the button combo, which would be a third place to branch if you wanted.
