King on point as always. Not sure about the rest, though maybe Mary if she still has a good j.CD and over 9000 invincible reversals like in XIV. Also, if she's as strong as the TGS build hints she will be, then Isla on anchor. The ease in which she seems to be able to dump 2-3 bars into one combo with two supers cannot be ignored.
Having Liz and Kula back would be perfect as it would mean all the protagonists and their rivals are back in one game.
So instead of the usual "one adult taking care of two kids" thing we have with the hero team and 3ST, we have mommy and daddy taking care of Isla.
