Nope there's plenty, you just aren't looking.
3dArcade, Mala, Dragon King, ect... they all have virtually limitless skinning options.
IMHO the console "skins" are incredibly ugly and uninspiring. Text list on the left, screenshot in the upper right, jpeg background, and that's it. Of course I and describing the skins for the front-ends themselves, NOT the m$ dashboard replacements, which have absolutely nothing to do with the emulators on the xbox. I think you are confusing the two, because without snapshots and proper game names (which aren't available in the dashes) you need to actually run the emulators gui to see what you are going, and they are quite ugly.
