There was a big thread on the Mito room about doing exactly this, I think the problem with putting a strut strong enough to instantly lift the hatch was that you needed to be 20 stone to get it closed again, never mind the strain it was putting on the mounting points.
It ended up going down the route of springs and such like to kick start the open, then the struts take over, or something like that.
Will have a look and see if I can find it, might give some tips.
