This is something I've wondered about. If your pickups are piezoelectric or magnetic, I don't see how the wood or body shape would effect the sound. The only argument I could see is if somehow the body of the guitar were affecting the resonance of the strings.
As you know, piezos capture the vibration right from the surface of the wood. Even the material used to adhere it to the surface (I'm talking about stick-on transducers rather than under-saddle models) will affect the tone. Perhaps try this: buy a Dean Markley Artist transducer (about $30). Stick it on the foot of your bridge with the grey putty it comes with and have a listen through an amp. Then try it on the soundboard itself. Very different tone. Then replace the putty with blue tack used for hanging pictures - much softer and will impart a softer tone. All this is best done plugging into a buffer that can correctly handle the very high impedance of the piezo, but it'll also be apparent with a simple direct to amp connection. Then try on different guitars and see for yourself if the guitar matters.
And with magnetic pickups, yes the string's unamplified tone is greatly affected by the body and neck woods (maple, mahogany) as well as the body design (Les Paul type with a hollow cavity vs solid). To my ear these variables have a big affect on the tone that the magnetic pickup captures.
Of course, I'm interested in seeing more about the science of it as music performance is so subjective.
