I wonder what happens if you try to touch-in with a Barclays "Onepulse"
Oyster card, which now has Paywave added. Something to try next time I'm
in London!

Barclaycard OnePulse cards always had payWave functionality, it's not a
recent addition - that was part of the original selling point.

Fair enough, but what will happen (soon) on a London Bus: which of the
two elements will "win"; or will it refuse to pick either, claiming you
are trying to use more than one card at once?
