I looked up a few videos of Jump Ultimate Stars and I think it would be possible to make in PFE. You can try out the free 0.7.1 version of the engine first, it doesn't have netcode but you can make sure that the game feels right before purchasing the full engine.

I have toyed with the demo and decided to purchase the full engine. I do have a new question now. Could I add buttons.. Like if I want to add a separate/3rd button for strong/smash moves not attached to the attack button, and to remove air attacks except for one air attack, done with the attack button and another air strong attack done with the newly added strong button. Oh and add a 4th "super move" button as well?
