However, before I use that, I was considering running some Mobil 1 synthetic in the gearbox for a thousand miles or so sort of as a flush. I'd drain the old junk out, fill with Mobil 1 then drain that after 1000 miles, to get all remains of the old stuff out with it, then fill with the Porsche fluid. I know that can't hurt things but am I wasting my time and money doing that?

Yes, you would be wasting time and money.
