For large case, I suggest getting rid of the pre-built drum modules and go for less but more versatile modules to build your own drums. This way you can: modulate drum pitch, decay, release, volume etc.
I am fairly new in modular also, so my advice is with heavy grain of salt, but I have done tons of drum programming and therefore not a fan of generic drum modules UNLESS space is an issue (as for my own rack).
Get some noise/sine/filters with bunch of gates/adsrs and design your own drums. Otherwise get a ready-made drummachine. Only thing I see problem with patching manually is cymbal, which can be complicated, especially if you are completely new to actual sound design.
