I shot wrecks with a Nikkor 16mm rectangular FE for years. The FE lenses are good for "outside shooting in" pics, but you going to be shooting manual to get the right exposure. Forced perspective (aka distortion) is a given with FE lenses, but is controlled with precise composition. Got to keep your planes lined up.
The two strobe rigs are definittely too large to go inside. (That was film and digital in an Ike hsg with Ike Substrobes)
So I switched to Olympus P&S and was able to shoot inside. The I went to a Cannon S90 in a Fisheye Fix hsg plsu INON D2000 strobe, and that allowed me to have small rig with one strobe plus the Inon 100 WAL which worked nicely. You really don't need to go wider than 24mm EFL inside a compartment but maybe in a main space like cargo hold? Silting up and backscatter are big problems in side.
IF you are penetrating make sure you can collapse your rig to get thru tight spots.
