Whilst I haven't specifically done this, I have done diskless booting
on a wired NIC and then switched to a wired/wifi lagg. Have a look at
http://www.bugs.au.freebsd.org/dokuwiki/doku.php/laggdiskless

FEC & LACP require support at both ends and so won't work. loadbalance
& roundrobin should work but aren't really appropriate unless your
interfaces are identical.

Yes. Once you create the lagg, the interfaces comprising it will no
longer work standalone and you can't atomically migrate the IP address
from re0 to lagg0 - hence the script linked from the above page.
