If Hood's sisters had survived, what becomes of Nelson?

If Hood's sisters Howe, Rodney, and Anson had been built, what would Nelson's sister have been called?

The sisters might have become carriers or altered treaty totals; a later pair could plausibly be Nelson and Collingwood.

If the sister ships had been further advanced, at least some might have become aircraft carriers like the Lexingtons. Completing all four battlecruisers before the Washington treaty would have left Britain with difficult disposal and quota choices. Any later pair of capital ships could plausibly have been named Nelson and Collingwood, although the treaty fleet structure would be very different. A surviving six-battlecruiser force could also have changed how Britain divided its capital ships into battle and battlecruiser squadrons.
