I would convert the S/PDIF signal from optical to coax at the TV, except S/PDIF over coax will only go 30' or so.

Spec or no spec, you can go much further than 30 foot with S/PDIF 'EASILY'.
That is, the spec guarantees that the signal can go about 33 feet (10 meters, which is 10% more than you specced). But the signal MIGHT go much further.
Try it. If it works, propose to use it for the $#$ it cost you to try it out, or to stick with wiring per the protocol at its cost.

I posted many many years ago about having to use a piece of speaker wire (18awg) to send the coaxial S/PDIF signal from a DVD player to an A/V receiver. That was about 25-35 foot and it worked perfect... over a piece of speaker wire, no converter, just spliced in.
That shows robustness of the signal that's not even hinted at by the spec.
I have also sent the coaxial S/PDIF signal from a bluray over RG59 about 60-70 feet with no problem.
Since I have never personally went 100 feet on RG6 with that kind of signal before, I can't say 100% that it will work. But with all my experience working with it, I can see no reason why it shouldn't work.
That's why I say to try it. If it doesn't work, you have proof that the next best thing to meeting the spec simply won't work.
