I'm not sure if this kind of device already exists but there's gotta plenty of comb filter chips out there for newer set designs. Would be an easy and interesting project that's for sure

A comb filter requires at least a one-line video memory.
For an analog comb filter, that would require finding a glass delay line from an old TV, not just a chip. For a digital comb filter, you would need the chip(s) that do(es) A/D and D/A and memory management plus whatever memory chips are required.
