New widget area with 2 rows of cells?

I'd like to add a new widget area with 6 cells set up as 2 rows tall, 3 columns wide. I want this area to have a continuous/seamless background, possibly with a border. Is this possible using the add widget tool within ATA?

I'm thinking I'll add this to the footer content creating sort of a top footer of featured content and a lower footer with typical copyright info.

Any suggestions? All advice welcome and appreciated!
