Thesis, The Aiming Point is located on the plane line and lifting the hands is a concern. If, My aiming point is on the plane line at the left rear quadrent of the ball. How the heck am I going to hit the ball and maintain alignments ???

You wouldn't hit the ball AND maintain alignments.
However, what alignments are you worried about and/or referring to? Again theoretically, let's say you wanted the hands and clubshaft to BOTH move on the same downswing plane into impact. That wouldn't happen in my example in my previous post. So that's one "alignment" that wouldn't be maintained - an on plane hand and clubshaft motion. If you started with a level lead wrist - then that's a second alignment that wouldn't be maintained.
