Distinguish Left click from Right click, without lifting fingers (MagicMouse)

So I was wondering whether it is possible to make a right click, while having both fingers (L & R) touching the magic mouse.
Background: It is a little annoying to me that I always have to lift my left finger up in order for the mouse to register a right click.

Unfortunately that's not possible, the Magic Mouse sensors don't provide a force property and I can not estimate it reliably at all .
