So would it be an ok idea to make one that just fits over the secondary
form and slide it down on the from to just above the last turn?  Sounds
like something I could implement rather easily.

Might sound really stupid and I am not sure why I feel compelled to ask
but here goes.
The corona ring is electrically connected to the secondary output
terminal correct?

MY CORONA RINGS ARE THE SAME DIAMITER AS MY COIL AND JUSE ABOVE THE LAST
TURN OF THE SECONDARY
