You might also try blocking the internal strobe with a piece of plastic
and using an external slave strobe like a YS 60.  Seen that done with
the Canon housings.

Check around for unit that has a sensor that covers the area where the
built in flash is that will trigger the main flash.  There's no
guarantee there's one for your housing, but there's usually some way to
hook up a strobe to cameras for which a housing is available.  You might
ask Ikelite.  They're pretty consumer oriented and probably keep track
of such things.
