I guess it's doable but if it comes to Timing things this counts as not legit again.

What could be done is something like this (just a thought)

press key the mouse is going to a defined spot (1 action per click) then click so I guess it's legit. Than do it this way: the mouse jumps (like you said) to next windows but after a click then click mouse again would be like, "Defined Mousemove Button" DMB, click, DMB, click DMB, click, DMB, click and so on could be done in under a second. If you understand what I mean.
