Super Gogeta, SSJ3 Vegeta and Vegito Blue (the friend's one) are very good at getting each other to super attack (thanks to the Over in a Flash link skill, which gives +3 Ki... plus the other link skills), and even though AGL Goten deals more damage (+70% ATK when HP is 50% or above), I think that... yeah, you can switch him with STR Goten, who would help SSJ Gohan to super attack (they activate all of their link skills, which makes sense since those cards are from the same movie), and maybe he could also help SSB Vegeta by changing orbs. Oh, and if that still wouldn't be enough to get SSB Vegeta to super attack, you can switch him with SSJ2 Goku GT, who basically always super attacks thanks to his passive.

But I'm pretty sure that Super Gogeta and the friend's Vegito Blue will take care of everything for now, so feel free to do some tests and see what you prefer!
