Hey. Not sure if you're still thinking about doing this or not, but you should know about Kong.

"Kong amplifies the drumpad signal and also converts it to trigger and velocity CV signals"
So this would get 2 drums into the modular environment without much hassle! from there you can do whatever your heart desires with those signals.
All in just 5hp.
Imma get one forsure.
