tweak aeropeek

Hi guys,

I am trying to find a way tweak the aero peek feature of windows 7:

Normal procedure to aeropeek a window is:
- selecting the taskbar button
- waiting for the thumbnail view to pop up,
- hovering the window thumbnail I want to have a peek at

I would like a window to be "aeropeeked" when I hover the toolbar buttons directly (which implies no grouping of taskbar buttons I guess, and possibly no thumbnail preview)

Any one has a clue on how to do achieve that?
