If you don't incist on using /etc/network/interfaces you could also use
systemd-network:

/etc/systemd/network$ tail -n +1 *
==> br0.netdev <==
[NetDev]
        Name=br0
        Kind=bridge
        MACAddress=<MAC-OF-INT-TO-BRIDGE>

==> br0.network <==
[Match]
        Name=br0

[Network]
        DHCP=yes

==> uplink.network <==
[Match]
        Name=<INT-TO-BRIDGE>

[Network]
        Bridge=br0


This assumes that the bridge will reseave an IP from a DHCP server.


HTH.
