Yes. Try using veth pair interfaces:
ip link add name veth1 type veth peer name veth2
You'll get veth1 and veth2 pair that act as a "wormhole". Now add veth1
to the bridge and use veth2 with your program in the way you used tap.

If you need second pair just repeat procedure with different interface
names.
