Two Column Layouts with 75/25 and 25/75 Split

Thanks for the great module. I've already begun using it and I'd love to see two more variations on the two column layout: one with a 75/25 split (on the middle and right columns) and another with a 25/75 split.

If you're using a theme that is fairly narrow in width (and one that already has a two or three column layout built in) it's pretty hard to add in an additional three columns in the node content area. So I'm forced to use mostly the two column layout options. But what I really need in the node content area is one dominant column for the main text and another smaller "sidebar" area for the related content. The 75/25 split would solve this.

If the main text column could wrap around the smaller (and probably shorter) sidebar column (perhaps by using a CSS "float"), that would be even better (but not necessarily essential). This type of float/wrap is implemented in the recent Acquia Marina theme.

Thanks for your consideration and kudos for your excellent work on this project!
