I was just going to request the same feature., I think? I'm not sure I'm understanding the request but one thing I'm personally missing is to be able to pitch the punch separately from the tail (i.e. alter both, but this might be difficult with midi) or to be able to pitch both the punch and tail up or down, but retain the timing separation of them, so the groove remains intact. Not sure this is super clear either.
Another thing I would love to see is improvements to the Punch Reverb section thingie. It would be cool if it briefly resampled the reversed punch + reverb, then reversed that again and mixed it into the end of the 1/4, so that it creates more of a suction feeling. I think that's kind of the idea with the current implementation but I just never get it sounding very good.
It would also be cool with more pogo parameters and options! And maybe also the possibility of having real highpass/lowpass filters on the kick parts, and an optional low octave sub OSC which can play instead of the sub bass in the kick sample... I have many ideas. Curious what you have planned!
