Can I install a SIM2.1 OE2 GP3.2 image on a DM800SE box using the Japhar NC3 SIM, and will it run OK?

It runs great with the SIM2.1 card with SSL84D.
I would rather use it than the OpenPli based images if it is possible.
The main reason is the Genini GP3 panel Utility it much more useful and user friendly.
