Login page content in header

Hi guys, need your help again. Using OC 2.0.2.0 I'm trying to display in the header, inside a sliding div, the content of login page, I don't know if it's possible, on google and forum I couldn't find results. I tried to copy/paste the code of account/login.php and login.tpl files into common/header.php and header.tpl, obviously it gives many errors. Below is a preview of what I want to achieve. If you can solve it please reply thanks.
