Looking to composite mod my RF-only Panasonic CT-9R10CT, any advice?

Found the above model for pretty cheap by me and I want to get past the RF only and add at least composite. I understand these are hot chassis but I've seen a few of these modded online so I am not too worried. I am using this Sunthar's which is actually for RGB, which is why I would like an outside view.

The schematic in the link above makes it seem like I would want to lift the leg of capacitor C10B furthest from the jungle IC and run my composite into the lifted leg through the capacitor into the jungle IC. I have a feeling this would mess my composite video so it may be best to run my composite video after C10B, bypassing it altogether, and into pin 33 of the jungle IC. I feel like in Sunthar's mod it is suggested to run through C10B because the composite video is used as a source of sync rather than actually composite video. After that I would simply ground my female RCA jack, using a 75ohm terminating resistor in between my jack's sleeve (jack's ground) and the CRT's ground.

Does this mod sound correct? I know most here like RGB mods but this is such a handy little TV and I want it to be useful for as many cases as possible.

RF only will most likely be a live chassis.
Just double check that it is not a live chassis before trying to mod the unit via conventional methods.
Most would give up at that point.

There's the Reflex RF from MisterAddons. You could also maybe try taking out the chassis and installing one of the ones on Aliexpress, if the TV would otherwise be worthless to you.
