But, silver mica could be a very strong error.
You could simple leave the original caps.They are good enough, and small enough.
Or if you want, but without great difference, you could try ceramic multilayer, smd.

Could you explain us why silver mica is an error ?

With SMD, I'd prefer NP0 material

Okay for SMD npo, i would say ceramic COG dielectric.They don't change ESL e ESR with increasing of temperature too, like or better than npo.imho
Silver mica: the problem could be the solder junction between leads and mica chips.Could be not so conductive, for age and oxydation.
Sorry sorry for my english...
