At least a couple of them are rated at 1000v by the way.

I'm not the world's expert, but based on experience and on the knowledge of engineers with whom I've discussed this in the past, the answer is No. The ceramic discs are too temperature-unstable, and you'd be adjusting the horizontal hold every 5 seconds. I know that All Electronics, Inc has micas, but they're here in the LA area. However, for troubleshooting purposes, you could parallel two paper caps, and that would be much better than a disc, and certainly better than leaky/open/shorted original micamolds. (if it's a .05, use two paper .022 @1600v). That way, you could order the micas knowing whether it's going to solve the problem.
