Converting the Bosch Metric Pinion into an English- Specification Pinion

At the drivetrain seminar at nationals, i think (and am probably wrong) that someone stated that they converted the metric bosch pinion into an english-specification gear by mating the metric pinion to an english gear and running them in union for about 15 minutes. I’ve been told that this is impossible - perhaps I am mistaken. Does anybody know the specifications of the english gear, if this process is possible?

Thanks a lot.

just pull the pinion the drill motor and make an english one and press it on.
