Sixteen battlecruisers and the infrastructure to build battleships

What if battlecruisers escaped treaty capital-ship limits and Britain built sixteen of them plus six fast carriers?

If that doubtful treaty premise held, Britain would have a stronger fleet and more infrastructure for rapid battleship construction.

Exempting battlecruisers from treaty capital-ship limits is a difficult premise to justify. If such an exemption nevertheless let Britain build sixteen battlecruisers and six fast carriers, its wartime position would be much stronger. The construction program would sustain infrastructure that could also build battleships. The benefit would include faster battleship construction as well as the existing battlecruiser fleet.
