The best way of doing this might be to modify Linux bridging code to
understand a bit more about how IEEE 802.11 access points operate and
allow it to bridge broadcast packets back to the same interface in this
case.

And that will not work. I think you can convinse Linux to route unicast
packets back to the same interface and even disable ICMP redirects that
are normally sent in this case. However, IP routing does not route
broadcast frames (like ARP request from STA1 to get STA2's MAC address).
In other words, you would need to modify Linux kernel code for this,
too.
