I mostly use C but i experimented with F so lesee...
after a 2c>2369A, you can prolly do another 2369A, but you wouldnt be able to connect 3c afterword. You do have the option to rejump and end it with a standard air combo though. I guess a 623C ladder right at the moment you land would be an option as well.
After you land, you would not be able to jump cancel after a ground normal in one combo, so you can only hope to rejump in a combo after a 623C since it wallslams and gives you enough nonrecoverable time to rejump and aircombo.
My personal fave thing to do is, in the corner, connect as many ladders in one combo as possible. Waste dat meter.
Just looking at possiblities, you can 2abc>2369jC>land>236a236a (too lazy to test) for an untechable ground hit combo, but the damage would not seem like that much. Chisui benefits with her 236a236a ender cuz she gets a decent amount of damage off it and it's a free bento setup. i guess ex throne would be an ex cancel option for FHisui... *thinks*...
