Nine can do the active switch with her 4P and still get a combo like Hyde does here, but it's either too slow or doesn't have enough range to be used as an unblockable for Kanji. The best unblockables with Kanji that I've found from the new set are Nine's 5P, Mai's 5P, Akihiko's 5P, and Merkava's 5P. You just can't active switch to them, so you'll only get a combo if they jump or backdash (but you can just do another unblockable after the command grab).
Have you tried this with the 3 wave of dlc?
