Hi Skip,
         In replying earlier, I overlooked the fact that you already 
have a rather low Lp. A better approach which avoids having to modify 
the resonator might be to build a driver secondary, add the extra Cp 
and run the existing secondary as a free resonator. The extra 
inductance in the secondary system would compensate for the extra 
primary capacitance. You could even add some more Lp if enough extra 
Ls is added.
