Would an early H-39 programme change Allied construction?

A patron counterfactual leads to a qualified answer about how a 1935 H-39 programme might alter British and French choices without causing immediate war.

Question

What if Germany standardized its new capital ships around the Scharnhorst hull, or instead replaced Scharnhorst and Gneisenau with H-39 designs laid down in 1935?

Short answer

An early German 16-inch H-39 would likely have changed later British and French construction choices, while treaty-era unreadiness makes an immediate preventive war unlikely.

Notes

Replacing the Scharnhorsts with a three-shaft, diesel-powered, eight-16-inch-gun H-39 design could have made British 14-inch King George V decisions harder to sustain. Treaty limits, disarmament, funding, and incomplete readiness constrained the Allied response in the mid-1930s. Britain formally ended the Ten Year Rule in 1932, but money for new battleships did not arrive immediately, while France also lacked the readiness for an early military answer. The counterfactual therefore changes later ship design and construction choices more plausibly than it causes an immediate preventive war.
