Having stripped the threads with a crank extractor and resorted to a
fork type ball joint splitting tool, is the resulting damage to the
plastic bottom bracket bearing holding-in-thing likely to be more
than cosmetic?

Don't think so. You can always leave it in.

And any suggestions on getting the right crank off? (Hasn't stripped
yet, but feels likely to. I don't think I can get the same tool in
without knackering the inner chainring.

I built a tool with lots of bolts and bits of metal to act as a puller -
with varying degrees of success...

I _might_ be able to undo the
bottom bracket without taking the right crank off, but I'm not sure.)

Shimano splined? Probably not.

Try loosening the bolt which holds the crank arm in place, then
carefully riding the bike. This can loosen the crank, but if you aren't
careful can result in you falling off when it comes loose, or damaging
the crank by rounding the corners (assuming square taper).

While I think there is a spare unstripped left crank in the shed, damaging
the right one now wouldn't be a disaster (whether its rounded corners
or bent inner ring). And it has an SPD pedal, so riding it with one crank
might work (or I could the spare left crank on first - why didn't I think
of that to start with?). Maybe when this wind and rain is over.
