Moving user navigation to top in Corporate theme

Hi,

I really like the corporate theme, and I'm having a lot of fun customizing it to my needs, but I need some help in getting the user navigation changed.. I want to move the user navigation into the search bar and make 1 handy user bar for easy access on the site!

I've attached a mock-up to show what I mean and hopefully someone could help me achieve this..

Thanks in advance!
