“The whole point is to fool them into thinking I’m a shark.”

I see a problem with this "submarine". Visually, I'm sure it is very impressive. But Great White sharks do not rely heavily on visual stimuli. Their world is perceived mainly by their sense of "smell" and through electromagnetic cues picked up by other sensory organs that we lack. They will not be fooled into thinking this sub is another shark simply because it happens to look somewhat like a shark. In fact, the electromagnetic noise this thing puts out would likely have unintended consequences and elicit unwanted behavior from the shark. This could range from spooking it to perturbing it.

Good Lord, I wouldn't want to be the one who has to "test" this sub in the presence of Great Whites. If the movement isn't right, it could have the unintended consequence of making the real Great Whites think that it's wounded. Have you seen the stats on the bite pressure in lbs/sq.in. of a Great White? Omggggggggg....
