As long as they can withstand the high inter-turn RF voltage. Unless
constructed as a single layer winding or as one or more very thin
"pancakes", RF chokes in this application will flashover in a very nice
(but destructive) lightning display. Sounds like they may be inexpensive
enough to try via the "smoke test"...

Safe coilin' to ya!
