I have a TRP hy/rd on rear, which has been fine. Hasn't fried. Figured I'd use that on front. Co-Mo, Santana and others put cable discs on front, so I assume they work without frying.

Yes. You should see my toolkit. Otoh, never had to bleed my hy/rd.

That assumes I need hydros. I use bar-end shifters and TRP RRL levers, which should be fine with cable or hybrid discs.

My DT Swiss Hugi rear hub on the Co-Mo has a threaded adaptor that would work with Arai drum.. I have Arai drum on our Santana, and I love it. But I can't see carrying the extra xx pounds 3,800-miles cross country just for the 5 miles I needed them. The TRP hy/rd on the back worked fine, plus I also have V brakes on the back as backup. Also, something like 75% of braking power is on the front, which is why I want to work on the front.

I don't care about sexy. I'm a 64-year-old dork, for chrissakes. I care about what works.

Because I want to try it, as I said. On our X-C, I met a bunch of fully-loaded cyclists on tubeless who swore by them on paved roads. So I'd like to try.

We tour on 60-70 psi. Is that high pressure?

Are Son disc hubs symmetrical? Don't they require dish?
