The
SS Norwich City left in the neighborhood of 5600 tons of debris on and around the reef.
That's liable to generate a lot of false positives.
I suppose if there's room, power, and bandwidth on the ROV, it might not hurt to add a magnetometer.
There are only a few pieces of the aircraft that are likely to generate significant magnetometer readings (engines and landing gear).
Here's a $6000 underwater magnetometer rated to 130':

http://www.quantrosensing.com/digital.htmIt's only good to 500'.
At EPAC, I think we were hoping to get gear that could go
down to 1000' at least. TIGHAR won't know until it looks
how far stuff tends to slide downhill from wrecks on
the reef.
