Is it possible to duplicate the custom header function?

Hi

I want to have two areas with a custom header, allowing the homepage to have two customized sections managed with the custom header builtin function.

With one, the user will upload a custom image just like twenty eleven.
With the second one, the user will upload his logo.

What I would like to achieve was the use of all the resize, crop, pre-set images, etc in the logo area, instead of making it a simple upload field.

Is this at all possible, or can the “custom_header” support be used only once in a theme?

Thanks
