Pushing 20A Grinfineon above 60V?

Without talking too much about this being outside of the specs and how it voids the warranty, has anyone run the 20A grinfineon that comes with the G310 kits on higher than 14S? I've used mine on 14s for years never had an issue, but am looking at buying the newer Dewalt Flexvolt tools that come with the 15s batteries and it would make a lot of sense to use these at some stage. The problem is 15s is going to be around 63V hot off the charger.

Controller specs:
Nominal Battery Voltage 36V-52V
MOSFETs 6x AOT460 <---------------------------------checked and these are rated a 60v
Max Regen Voltage (+/- 2%) 58 V

Regen voltage obviously isn't an issue on the smaller geared hubs, and the surface charge on a 15s pack pretty quickly drops below 60v. To keep this in perspective, if we were to consider 60v to be the rated limit of the components, 63v would represent pushing them 5% beyond this for a short period of time at minimal current rates.

What are people's experiences?
