And no need to destroy the cabinet (which you would by banging it apart). Typically the face frame of the cabinet protrudes into the stove opening a half inch proud of the body of the cabinet. The fastest and easiest way of widening the existing opening with no risk is to shave the face frame and grind the edge of the top all done on one side of the opening

The cabinet face and side and stone are all essentially flush on both sides. I definitely do NOT want to try to remove the stone from the cabinet unless I absolutely have to.
And before I tried to disassemble the existing cabinet, I'd just make a new one.
