Hi John!

❝ Could I hypothetically strip the two treatments (successful test formulation and the reference) and re-run stats in a two-way crossover fashion to re-evaulate the data?

(my emphasis)

See this goody (slides 60–67). The title ‘Don’t try this at home!’ tells it all. You are not the first one having such an idea (see also here).

❝ Would that stand a chance with regulatory?

Close to nil – unless you run sufficiently large simulations demonstrating that the patient’s risk is preserved. Not a trivial job.
