As has been previsously mentioned the Motorola MC1377 is probably the most
available chip for this purpose. It does require a moderate amount of support
circuitry, but that's life in the analog universe. The worst problem is that
you need a small analog 'delay-line' that is not readily available at the
retail level...

I have a similiar problem. I have a popular computer produced by Toy
Computer Inc., which produces an RGB 80 column signal, and a
non-standard monochrome signal at higher-than-NTSC scan rate. I only
have a monochrome composite monitor. Twould be nice for the twain to
meet... the RGB signal sounds like a perfect source to mix and stir a
composite signal for my monitor to eat.
