Not just STP, but all the data structures in the code are set up
1-N.  For example, there is a pointer in the netdevice structure that
contains the bridge to handle the received packet.  What would it mean
to be part of multiple bridges? Would received packets be process N times
by each bridge?

Probably not. What are you trying to do?  Might to be bridge the
physical LAN and do any filtering based on tag using bridge-filtering
(ebtables).
