Eclipse: keyboard shortcut to move tabs around?

Is there any way to setup an Eclipse keyboard shortcut which will split the current editor vertically and put the current tab on one side? For example, turning this:

Not directly with eclipse (3.4 or 3.5)

The closest plugin I have found which might enable what you are looking for is the Split file Editor

Ctrl+6

Usage: Open a file in Eclipse, then select Window -> New Split Editor from the main menu to open a split editor of the file.

(not exactly what you want but:)

Split editor opens in a new tab as opposed to appearing within the existing tab

(so while there may be 2 instances of the same file editor, you still have a situation with one file on one side, and the other files on the other tab group)
