Found something with Akira you'd probably want to check, dunno if we can find a use for it. Basically 6KP on a Back turned opponent, if you whiff the K and let the P hit their backs, it causes a fainting stun. Couldn't find an open space one. I managed to get something off an invisible wall setup with 214P+K and landing 6KP if they don't SE but that's all I found.
