The 5H>IAD j.P stuff only works on Justice, she's just tall.
The sideswitch is 22D>FRC>j.P. The FRC has to be done on the first frame and the j.P has to be inputted the exact frame after, so you have to FRC with KSH (cuz you can't press P two frames in a row).
The IAD loop coast to coast is practical tho.

Same combo works from throw. Chipp's throw is wack and the opponent isn't actually knocked down until like 4F after Chipp recovers, so he can link into 2P against Pot and Justice (+ Banki and FB Beta Blade vs the rest of the cast).
