In a front impact, the A pillar will almost certainly buckle at those cuts. Maybe not a lot, but the most significant thing is that your door will probably be jammed shut (or both doors, if you've cut both A pillars and the car is hit more-or-less squarely head on) because you've weakened the rectangular structure that is your door frame.
You might, although this is a longshot, find that when the car is jacked up at one corner, you can't open the front doors anymore, or close them afterwards. I would recommend leaving them closed while you jack up the car anyway, since the first sign of a buckling A pillar will be your windshield cracking.
