I'm looking to remedy a leak I have a in the overflow portion of my tub. Most of the water damage (image attached) from below came after a bath and prior owner, so now we only use the tub for showers. The most similar setup I've found is the Watco Innovator (image attached) online. It requires a washer behind the tub, star nut, and cover. Water gets between the star nut and tub. If i tighten the star nut too tight, I can no longer fit the cover. I think that would mean that the washer behind the tub is worn out. I do not have access to the plumbing to replace that washer.

Is there anything i could do to remedy this, without access to the back? I think even if I did cut open drywall for an access hole, getting a washer back around might damage more plumbing due to having to pull the pipe back out of the tub.

Could i just tighten the star nut and ditch the cover, which is not aesthetically pleasing? Add a rubber washer between the tub and star?

Any general advice would be greatly appreciated!
