The list of supported players is on the front page (www.rockbox.org), your player isn't listed there, however, if you're interested in working on a port for it, you can find some information on what you'll need to do here.

The answer to the general question of whether it's possible to install a new firmware to a device that uses MTP is "yes".  Actually producing a new firmware that works with your hardware is a separate matter that will involve a lot of work. 

If, after reading the link that karashata posted, you feel you are up to the task of porting Rockbox then you can create a topic for this player in the New Ports forum if one doesn't exist already.
