> do you happen to know whether it is possible at all to do IP bridging on KVM/QEMU with a WiFi adapter?

Yes. Depends on how you want to do it, but yes. You can put everything on a bridge interface, or you can do a virtual bridge and then there's effectively a simulated network and you can have the host machine do the routing. You can also do both:

I think that wifi adapters have trouble being a bridge interface, so the virtual bridge might be the easiest way to do it.
