Paul-- I don't know if this technique is "kosher" or not, but I often practice with my capo on the 2nd fret (e.g. shorter scale) to get the coordination down, then back it up to the 1st fret, and then take it off... gradually increasing the scale in the process...
This might help your transition to your longer scale Zouk...
