Which console only outputs in RGB 240p?
The only one I can think of is the Amiga 500/2000/3000, but, there is a slightly different way of doing it with that computer since it already has the 'Y' signal on one of the pins of it's RGB connector with the composite sync included.

In European 90's, the SCART plug in RGB mode was:
-> 1V/75ohms composite video input with or without color subcarrier, sync/luma ratio 30/70%
-> 3x 1V/75ohms  RGB 0-100%
-> 1 control pin for incrustation 1V / 75ohms

very often in RGB product, the composite video was PAL, even for the French market with SECAM color process.

In the analog TV set, the bandwidth was ~8MHz in RGB mode from the scart plug to the CRT. It was a great improvement. (vs ~3.5Mhz en PAL/SECAM).

It's an interesting project, don't give up !
