You might get somewhere by creating a bridge(4) interface, adding em0 to
that and adding a vether(4) to the bridge. dhclient would then run on
em0, adding and removing dynamically assigned IPv4-addresses, while
the vether has a static address:
# ifconfig bridge0 create
# ifconfig vether0 create inet 192.168.100.200/24 up
# ifconfig bridge0 add vether0
# ifconfig bridge0 add em0
# dhclient em0
The proper incantations in /etc/hostname.{bridge,vether,em}0 are left as
an exercise for the reader.
