Sounds like an interesting project! (Extra interesting because of the the short deadline;)
From the Help menu, open Kyma X Revealed. Starting on page 196 there is a section on on RE analysis and resynthesis.
In the Sound Browser, you could also Search by Sound class name for 'vocoder'.
And in the Kyma Sound Library/Cross-synthesis folder, there are additional examples of different kinds of cross-synthesis.
Hope that's helpful for a start. Let us know how it goes or if you'd like some suggestions based on the actual source materials you're using.
