I've pretty much completed it now, and I'm quite happy with it. I managed to succeed in getting a full resolution rendertarget (the previous shot was half resolution) and a 75% FPS speed by going to vertex-based. It's not as smooth as the old pixel shader, but you'd really have to be looking to notice.
The real irony here is that I also tracked down the real reason for the huge FPS impact of my old render to texture water updates. I won't be reverting them though as my current pixel shader is perfectly good, and doesn't need as much video RAM.
