This seems to be another shot of it, when Godzilla is again dragged underwater in the final battle; unfortunately we don't get a look at the dorsal fins, but the long, slender fingers (seen better in this behind the scenes pic) are consistent with MosuGoji's.

I definitely agree the screenshot is of MosuGoji, given the shape of the finger claws, though it seems like a more Daisenso-esque head was attached. As for the production shot, it's hard to tell, but the fingers almost look a little different. Then again, the feet resemble MosuGoji's.

While the head doesn't belong to the original MosuGoji, the one visible dorsal fin definitely does

Yep, that's a dead ringer for a MosuGoji plate. According to The Pictorial Book of Godzilla, these three images also depict the MosuGoji. The caption on the last one claims the spot on top of his head is from where Gomess' horn was removed. I can't see the plates well enough to confirm or deny, but there you go.
