US Tesla charge port retrofit to CCS2?

I once asked at the service center here in Amsterdam, and they said very flatly that they don’t do charge port retrofits for different regions. Which is a shame, because it seems like it would be pretty straightforward to do.
 
I have the same issue in Malaysia with an imported M3 from Japan also using TPC/NACS while local standard is CCS2. I have adapters but they didn’t work on superchargers. Would be keen to know if anyone have successfully retrofitted?
I managed to swap the ECU to 20-B. The supercharger works on my JP cars.
You need a CCS2 to TPC adaptor with the switch, I believe to switch on/off the resistor.

Conclusion, it works.
