GP2X

As I said, the simulators are basically "Rockbox as Software"

All you'd have to do is make it run fullscreen, and adapt it (and of course get playback running in the sims well).

Why should we overwrite the firmware if we can already achieve all the things rockbox features with the current firmware?

Where do you get this idea of overwriting the GP2X's firmware from? Rockbox runs alongside the retail OSes of the iRiver and iPod models (I'm not 100% sure of the Archos' and the X5 is on its way to dual-boot), so that is clearly one way to approach it.

FWIW, if it's achievable (as it seems), you'd be best porting it as an app within the GP2X Firmware, rather than a separate firmware as with the other Rockbox targets ...

Oh ok, I didn't realize that. But wouldn't it still be more effective to use the already available libraries to improve the audioplayers that are already out there? I always understood rockbox as a program that is made to enhance the capabilities of mp3 player (well... mediaplayers) that cannot take advantage of an open development structure like the gp2x.
