Customize SiteCatalyst interface based on Report Suite selected

I would love to be able to change the menu color or something when someone is in a different report suite.  

We have two main report suites that we use often and run into a lot of user errors or questions (and potentially bad analysis) when they forget to change which report suite they are in.

That being said, is there a way to customize the look + feel of the interface when one report suite or the other is selected.  Even if it is a different background color for the menu navigation on the left.  that would be a huge help.
