Default Replacing low value electrolytics with ceramic?

So I disappeared from working on electronics for quite some time. I'm unboxing my ancient projects and want to resume some of them. Unfortunately, my knowledge is a little rusty.

I've always liked to do full recaps on power supplies. My cap supply isn't perfect and I do not have any more 0.47F 50V caps. I do have some ceramic caps with that value. Can they replace the lytic without issues? If I remember correctly, their max voltage drops rapidly after getting hot. Is that correct? If this isn't a good idea, I doubt the cap will cause any problems. It's by the main controller/exhaust so I doubt it will get hot or fail but I like to be thorough.
