Not a stupid question at all, vocoders don't change the pitch, they 
impose formants from another source on target audio, like a fancy 
automatic set of tone controls.

  BUT, if you run drums in to analyze as formants, then use a built-in 
oscillator (or any sound source with controllable pitch) as the target 
audio, you can "change the pitch" of the drums by changing the 
oscillators frequency.

Not at all pitch shifting, but for things like drums, vocoding may sound 
better…
