I would not be at all confident that the caps you found will work. There is the issue of equivalent series resistance -- ESR -- which dissipates power if the cap is carrying current, which it certainly is. I bought a bunch of HV caps without knowing this spec for them, and lived to regret it. Luckily they were in an antenna matching network where it was easy to see them smoking. :)
