You can implement multiple high-level main menus, because Cowon's design supports three alternatives... just properly named mainmenu1.swf, mainmenu2.swf and mainmenu3.swf.
However there is no equivalent in the lower-level sub-system UCI's. The music interface uses music.swf. There are no alternative names which are "triggers" for the UCI, so you can only have one alternative and functional music UCI installed at a time.
