Remember I am a hardware person. The PSU is as much a part of the machine 
as anything else. Some PSUs have rather interesting designs, too, which 
need to be preserved.

Hmm... IIRC the C64 brick is potted, and almost impossible to repair. 
Unlike the C128 brick, which is trivial to open, and not hard to repair 
(I've had mine apart).

I think what I'd want to do in that case would be to build a replacement 
PSU that followed the design of the Commodore one as closely as 
possible, but which was repairable, and used generously-rated components 
so it was more reliable. But I would not want to replace the whole thing 
with a switcher, which is totally non-original.
