Yeah, and it's never exactly worked out well. It's worth remembering that Bob Moog did make a drum controller for a hot minute, but that item didn't stay in the catalog very long. The nuance of all of the various drum strike techniques, incremental dynamics, etc just don't come across well in the analog domain. You really do need MIDI to break down those increments so that they come across in the electronics. Also, let's say you want to do a rim shot. Now, if you have a percussion controller that can recognize that as a different sort of stroke than a simple head-strike, then you can keep that very basic stroke in your repertoire. But without that additional sensor, doing any sort of rimshot, or for that matter anything other than a basic 'thud-on-head' hit, becomes totally pointless. And a basic contact mic setup will reduce things down to that level of basics.
A more sensible...albeit more elaborate...option might be to investigate some dedicated percussion controllers, instead of trying to make actual drums behave like not-drums. You're more apt to get into a tasty e-percussion area with something like an Octapad than something that requires loads of constant adjustment. Much lower maintenance, to be sure. Then to get from it to Eurorack is just a simple matter of MIDI conversion of whatever flavor suits your playing style best.
