“forcing” default color scheme to all users

I’ve recently stepped up into the webchair for a student organization at my school, and had some great ideas for revising the groups website, but need some help!

I love the new 2.5 admin redesign, but was wondering if I could change the default admin color scheme.
-wait-
-let me explain further-
I am aware of the wonderful new features of 2.5 that allow users to create their own color schemes and select them through their user profiles. I love this aspect of 2.5.
I want to know if I can “force” all new users to initially have a custom color scheme that I define selected.

For example, could I have all new members by default use “Iowa Student” color scheme instead of “Fresh”?

If possible, I’d love to keep the option for them to change to another scheme if they so please, but thats a secondary goal.

Any Thoughts?

Thanks,
