Canadian Queen Elizabeths and the case for F3

What would have happened to the proposed Canadian Queen Elizabeth-class battleships?

Their operating cost could have turned them into an imperial gift. Three additional Queen Elizabeths might then have strengthened Britain's treaty-era case for the F3 battlecruiser instead of Nelson and Rodney.

The proposed Canadian Queen Elizabeths could have formed a Canadian battle squadron or become a gift to the empire. In this counterfactual, the maintenance bill would probably push Canada toward transferring them to the Royal Navy. Britain would then approach the Washington Treaty with eight Queen Elizabeths, five Revenge-class battleships, and its surviving battlecruisers. That stronger existing battle line could improve the case for obtaining 16-inch guns through the F3 battlecruiser design instead of adding Nelson and Rodney.
