The OP reported 2 problems. What I posted was addressed at the second -
viz. getting the screws in straight. I don't see why that requires
pilot holes drilled "right through the door". Nor do I see why the
drill has to be "absolutely square". But then all I was after was
something better than can be done when there's a big knob in the way.

Because it is often slight misalignment that causes the handles to stick.
It adds friction to the system.

Speaking as an expert on the making and bodging of errors, I feel your
method will only make the original misalignment worse, and not leave the
option of moving the second knob in the opposite direction to the first!
