Splitting Header horizontally, how-to for Acquia Marina?

Right now, my site's logo is taking up the space between the Header Top and Header sections. My logo is left-aligned so on the right side I have all this unused white space. I'd like to put it to good use by putting a block in there, perhaps the search bar or the language switcher block.

So one question:

1- To do this, do I need to add a new region? If so how?

And one feature request:

1- Could future releases of Acquia Marina have a Header First and Header Right region added?
