It would require a good deal of work, and I feel like if they do it at all it should apply to all bodies of water (so the invisible walls we have at shorelines would need to move back a lot). I'd also urge them not to try messing with underwater combat too heavily if at all because it's usually so bad, though maybe that's just my experience with GW2...
