I just tested 240p specifically since the other day I was trying this image shift with 480p off my modded OG Xbox which outputs RGBS via a special Frozen cable (actually a weird flavor of RGsBS so maybe that doesn't count as pure RGBS).
So on 240p RGBS consoles, tried them on 2x Extron RGB 203 Rxi's (one set for DDSP on I think, and the other with that off so I can shift the image) and SNES didn't work ("no signal" shown on the 203), Saturn worked, went back to SNES and it then worked... NES worked, Genesis wouldn't work... SNES wouldn't work again (but then did work on another try lol... and I made sure to launch a game - since I think the SD2SNES menu is in some weird 512x448 mode and I wanted straight 240p and that didn't help again).... so sorry to say I might have jumped the gun and Extron RGB's don't like 240p RGBS 100% of the time.
This is weird as I know the mod of the CRT Gaming reddit uses a 203 (or similar Extron) to center either his MAME setup, or his real arcade boards (forget which, maybe both), but could be similar to how the Extron RGB's only like some lower res signals and not others. There's also some internal jumpers in the 203's dealing with sync but I honestly don't comprehend what the manual says about those.
I know there's some simple circuits to split RGBS to RGBHV, and would be curious to see if the Extron RGB when fed pure RGBHV would then take ANY (even low res) signal – or if it's still picky. Problem is I would normally use an Extron RGB to begin with to do something like this myself as that's what I have on hand! I know the Extron RGB can take RGBS as an input (manual also says this, and even says "Horizontal frequency 15 kHz to 150 kHz, Vertical frequency 40 Hz to 140 Hz").
**EDIT** forgot to even answer how mine is setup. My console cables either end in 4x RGBS BNC's, or use SCART to BNC breakout adapters. Everything gets plugged into the Extron Crosspoint 3232 switcher. Crosspoint then outputs to the Extron RGB's via an Extron 5xBNC (RGBHV) to VGA cable (Extron RGB's have VGA/DB15 inputs only - output are BNC's).
