To me, the best solution for this problem is to have a race pump built, with a TH stator as opposed to the metric stator, and upgrade the input shaft at the same time, to the larger TH spline. That gets you a better stator and a better input shaft, which will be less likely to fail this way later. It also allows you to use a TH style converter. Yes, it is more expensive. But broken parts cost money, and usually a race.

The metric input shaft is rarely an issue. If anything, it's the connection of the shaft to the forward drum that fails.
There are pumps that have an upgraded metric stator support installed to solve this problem. Like a 200-4R, a stator upgrade goes a long way to making a durable long-life pump.
