Lightened ring gears, REM polishing, light bearing preload, thinnest possible diff fluid you can safely run

Do you have any experience with lighter "gear" oil? I know so guys have seen a bump from using engine or trans fluid but there gears ended up scuffing. I've heard of a Gibbs zero weight?

What about a dry sump on a axle?

Whatever gear oil you use needs to be capable of providing the shock loading protection that the oil is designed for. When I say the thinnest possible you can SAFELY use, I'm not talking about 0 weight engine oil. I'm thinking more along the lines of 50 wt gear oil, provided it can still provide not only the proper lubrication it needs too but also shock loading, heat, scuffing protection, etc... An example would be someone going to a straight 75wt instead of running a 140 wt....... I'd never run engine oil in a diff as its not formulated to provide the protection the gears need. Two different animals altogether.

Is there somebody over here who has experience with ceramic bearings in a gearbox?

What about things like the Red Line Lightweight and super lightweight Shockproof gear oils?
