As an example, my 26x2.2 Race Kings are rated about 20W per tire, while there are MTB tires at more like 35W per tire.

Not to argue, but sooner or later you will be going downhill. And that upright position is a real killer.
MTB’s are a totally different animal as rolling resistance can be good or bad depending on the terrain. I’m sure there are those here who don’t want lower rolling resistance over wet slick surfaces.
My point is the rider position is a bigger detriment than a marginal tire gain. As I said a good quality, high thread count, lightweight folding tire is a good choice than splitting hairs on this or that particular tire “for a hybrid”.
