Thirdly: Group Super Attacks. What do?
I guess the first part of this question is to ask if it's even possible at all. Taking the Crew from my previous question into account, they have two techniques that require all four of them to use succesfully. So the question is: Could two (or more) characters combine their abilities and pool SP into a stronger Super Attack? Like two characters spending 2 SP each for a Tier 2 combinaiton attack? Or something along those lines.

As it stands, there is no way to combine SP of various characters, especially between PCs and NPCs.

For what you said above, I would recommend creating a Summon or an Attack Super Move that would serve the same purpose.
