Sounds like it might be OK. For some reason I had it in my head that French pedal thread was 14 x1, but of course it is 14 x 1.25 as marked on your pedals. A 1.25 mm pitch is extremely close to 20 TPI, so a thread diameter just slightly larger than the nominal 14mm might indeed make it OK for BSC arms. This was no doubt the thinking of TA engineers. Surprising someone didn't try this years ago, when French thread was a lot more common.
