I'm pretty trash at fighting games so idk how optimized this combo is, and I dont have access to the game atm so I cant get the exact numbers. Maybe someone could test this out and see if its any good? I've been using it a bit in training mode.
Throw > 214(B) > 6B > 5C > 5D > 5D > 5D
Im sure theres some way to string moves together better to optimize it but the general gist is to use the full charged 214B special after a throw and then combo from there. It does decent damage and it's easier to land than the 214C throw combo, especially when out of the corner.
