Hi Didimo,
officially you should fly the EHM painted airplanes... because that is why we paint them for the pilots

But.
The panel is a different story. Because, everybody have its own beloved panels for each types, and I understand it is not always the same with the one we provide. That is not a problem. You can install (or simply alias) and use any panel you want to your aircraft, and only because of the panel, you do not need to choose a different model or a different painting.
If you still have technical questions about it just tell us
