Yamaha DTXpress/DTXplorer/DTXtreme

[Edited]
 
Hi, I'm thinking of some creative routing and connection options...

I have a DTXpress I pad set with extra cymbal and drum pads, dual & 
single trigger. I'll likely get more pads... I also have three drum 
modules, the DTXpress I, DTXpress III, and an Alesis DM Pro module.

I was thinking about using all three drum modules for 
selected/prefered drum and cymbal sounds, then routing the various 
selected outputs into my mixer. 
Obviously with multiple modules I can run individual drum sounds out 
for treatment of say the snare, for added FX's. And now I'll have 
the capability to run a single drum sound into a recorded track. 
 
With what I have I figure I can have about seven different cymbal 
sounds. Maybe even alternate Hi-Hats and extra toms etc...
 
As for the snare I was thinking of even putting a "Y" adapter and 
split the pads triggered signal to two modules to combine sounds, 
similar to layering sounds in one module.
I thought about even using a selector switch somewhere convenient to 
route, say the snare pad from one module to another independently, 
and I could do this with other pads as well. This would be similar 
to a patchbay, without having to plug and unplug cords. In fact, I 
could make a Patchbay multi-selector switch box to route selected 
pads that I may want to switch between the modules.

Not sure which module will control wich cymbal or drum pad at this 
point. But I figure the DTXpress I module has the least impressive 
cymbal samples...?
 
Any of your own thoughts or problems with my thought? This may be 
interesting to hear some other idea's.
