Would this work?

Thanks.

Increasing voltage and gearing at the same time is not a good idea. Check the temps, you might even want to gear down. If I remember correctly, I ran some 9L's on 14 cells with a 16/66.

What's the worse that good happen.

On 16 cells? The worst? Probably a demagnetized magnet from too much heat.
