There isn't much to go wrong with these things apart from the bearings. I wonder if people sometimes confuse the natural notchy feel of a dynohub with the way they sense crunchy bearings.
I have not ventured inside an SP hub, but I have salvaged an old Union hub which was a forerunner of the Schmidt and I did explore a Shimano just to see if it was possible to service the output side bearings.
Spoiler alert, it can be done.
Unless as you fear, the cups and cones are not salvageable. Then it is probably a no go.

The funniest notchy dynohub was my SoN XL. I didn't think about the fact that a TS-2.2 truing stand shorts the hub. I thought the hub was broken. I only realized what was going on much later.

That's certainly not a trivial disassembly, but it's not beyond what someone could do if they have general experience with hubs and pay close attention to what is going on.
The matter of getting the cup and cone located properly on the axle was something I wasn't thinking about either. I imagine you'd figure it out quickly, though.
Looking back... is it necessary to remove the dynamo coil from the hub shell? Aren't the cup and cone accessible w/o removing that? If you were going to be poking around the wiring, or worried about internal corrosion, then there would be a reason to look inside.
Again, excellent video! Loved the "pull start" of the hub.
