You may have missed it Tod, but two solutions were given and 

1.) The suggestion was offered and a working example given (along 
with a history of actual problems) of using a latching vacuum relay 
or other vacuum relays. A 5kV or larger vacuum relay would have a 
safe margin if power is kept below a kilowatt or so. 

2.) The suggestion was offered of using a much more simple 
solution of switching a base inductor or series capacitor in and out 
and just leaving the hat connected in place (which would also be 
more efficient electrically).

Those were two simple practical working solutions....especially 
number 2 which would be the most simple system and the most 
rugged and efficient electrically...and they were immediately
