Nothing is impossible, but there comes another problem - you can not always be sure that all those buttons and menues will look nice with all kind of different pictures that you want to change every day or week… buttons are usualy in one or maybe two color… everything that has more than two colors starts to look silly…
I don’t know, maybe someone decide to make skin like that… ;D
