Ok so I'm building my revised BnB on paper because my old one was a little short of a kill combo, and I think I've got a good idea on what I want. I don't know if this all works, I might have to lose a couple hits for hitstun or the amount of time devil trigger lasts, but this seems like it should work on all characters from mid screen:
Jill/Dante:
2LMH4H(Feral Crouch Cancel), Somersault Kick(Jump Cancel), Flip Kick, Low Sweep(Feral Crouch Cancel), Somersault Kick(Jump Cancel), jHS, H4H xx Cartwheel Kick, Raven Spike DHC Devil Trigger, Cold Shower xx Stinger(Bold Cancel), Volcano(Jump Cancel), jM(Double Jump), jH xx Air Play, jH xx Killer Bee, A1(Arrow Kick), S, jH xx Air Raid
If anyone has any insight let me know. This should have a lot of flexibility and can pretty much start from anything.
