Well, with my Himes, I can't figure out how to do double Full Bursts. I can do ~30m off-element with Water Vigor build, doing FB on turn2 before I lose much HP. Asherah Awakened is +40 to all, Neptune is +50 burst to Medea thanks to double Wool. I believe it is the same setup that is used for double FB on Water, but I'd need to have Water Diana replacement for the second full burst, I think.

With no Wind Atum, Water Diana, Ymir, Michael and Aether, I think I am basically locked out of double full-bursts from all elements. I will probably finish around rank 100, which is by far the lowest I've ever been, but what can you do.
