Yamaha DTXpress/DTXplorer/DTXtreme

I'm (soon to be) getting a DTXpress III kit, and was wondering if I 
could do the following?....

(taking a tom input as an example...)


Since the tom inputs are 'dual' inputs (trigger and switch) would it 
be possible to put the tom and another mono pad into the same input 
socket but wire the tom to the trigger (as normal I presume?) and 
the other pad to the switch (then assigning the switch to another 
sound) and therefore get two different sounds from one dual input?

I hope so, because the only thing I find restricting about the 
DTExpress is the minimal amount of 'connections' you can get

Cheers
