Good bypass caps I would bet. It would not hurt to have a few of
these on hand.

You are going to end up needing 35-40 of these in series to get
the proper value. This leads to problems in pulse discharge
operation, and performance suffers. For the money, I would go out
and buy some 60 mil or 90 mil low density polyethylene and build
some homemade plastic film pulse discharge rated units.

These can be made to work by assembling a block of series/
parallel wired caps and submerging the block in oil to 
prevent flashover between the wire tails.

These are not bad ideas really. They are a ways away from an
ideal solution, but it does show you are thinking about how to
press available components into Tesla tank circuit service.
