I tried this once, when I had left my dark-cloth at home. It was near to impossible to either compose, much less focus.

Consider getting a good loupe that's intended for focusing on a ground glass. You can find them made by Schneider, Rodenstock, Fuji, or Toyo. Or, others? For me, it was literally a revelation when I went from a cheap loupe to a good one made by Schneider.
I have this loupe (upper left in picture, made by Schneider): https://rolleiflex.us/products/frame...series-cameras

I was under the impression that it's perfect for focusing on a GG as well. No?

Yeah, a dark cloth is at the top of my list, right behind film :-p.
