You mean instead of the Ocean Server module? I thought you actually ment
an image sensor ;) But considering the specs probably only
accelerometer/magnetometer. Most likely a daughter board is prefered
considering the space *and* the magnetic properties.

It might be that a dedicated processor in a feedback loop, gives better
results, for example an ardupilot interfaced to the Elphel. Opposed to
the Elphel doing the k-filters etc.
