Mike,

Bob Svangren of the Northwest coil builders tried something like that,
except his extra coil was attached to the secondary directly so there
was magnetic coupling to some degree between secondary and
extra-coil.  But I don't remember if he saw any particular advantage.
I think Bob used the grounding method you mentioned.  If he had
raised his extra coil higher above the secondary, the setup would
have been exactly as you have described I think.
