Seems hopeless. I don't figure any possibility to give possibility
to give be users/user groups a CSS-file in order to tailor BE user 
interface. I get just installation level control for that.

I tried to create more flexible skinning.
What I get

1) installation level alternative module icons

2) installation level  alternative post style sheet file

3) user/user group level alternative module icons
