Yes.
That is exactly what I must do, (short torso with long legs).
Upon having knee issues, I started reading all I could on fitting, and found that I needed to ditch the setback seatposts and go to straight ones.
The knee issues are gone, *and* I am much more comfortable on the bike.
Or will that change the handling of the bike?
Considering that 2/3 of your weight on a road bike is on the rear wheel, and only 1/3 on the front, (I measured it), going to a less rear-biased weight distribution can only *improve* handling, especially when climbing steep grades.
