This is really interesting. I had a similar idea but I have not the skills or time. The problem to solve was how to write on this clut without additional address bus. A gpio or some magic color sequence switches on/off the clut in write mode. At that point the RGB data are interpreted as address, value touples.
The drawback is that clut can be changed only on the vblank.
A new vidiot savant could also transform halfbright mode in a real 64 colors mode, and as you said perform yuv to RGB conversion for a yuv ham mode.
Please do it
