By Zune layout, do you mean something like current music widget for newgen (that displays few random artworks)? It looks nice. But a control widget would be more useful I guess.
Have you seen the media control widget by poiru for Omnimo? It's a control widget with artwork display, other song metadata info like song, singer, album etc. And it supports almost all major media players. In options one can choose player like WMP, iTunes, Zune, Foobar2000, Winamp etc.
Something like that would be great! (or am I expecting too much?)
