But theoretically, is it possible to create more than one bridge on one interface?
No, because that would make no sense whatsoever. Having a bridge means that any network traffic received by any bridged interface is also received by every other one. With the same interface on multiple bridges, because it receives all network traffic on one bridge, and because it is also on a second bridge, means that all interface on the other bridge also receive the same network traffic.
Which is exactly the same as if there was one bridge in the first place.
