This definition corresponds simply to a pitch transposer or Harmonizer. 
But I think, you want something else...:

...you want to transpose the base frequency of the voice up, but you 
want to avoid the mickey mouse effect. Yes thats possible, and it can be 
done with a vocoder basically as you describe: transpose the woice with 
an pitch transposer up, and then patch the analysis to synthesis section 
shifted one or two bands down. Basically it works, but it still sounds 
very vocoderish. For a minimum of satisfying results you need a very 
extensive prprocessing of the voicesignal for the usage as carrier.

In the digital realm the complete task can be done much more impressive 
(see Rolands VP9000 or Melodyne from Celemony).
