[O.B.Left]

My Irons are perfectly Soled when the Clubshaft is on an angle half-way between the Turned Shoulder Plane and the Elbow Plane. I use Hogan, Apex Irons with 1/2" longer Rifle Shafts.

The TSP is only a referenced Plane angle. No problem for a Hands controlled Pivot Swing to drop that a couple of Inches.

Not sure what you mean by "Referenced". Homer was pretty specific about the shiftless swing being along the TSP I believe. How else could the right shoulder take the hands down plane in startdown if the turned right shoulder and the hands aren't on the same Inclined Plane to begin with at Top! Maybe if you forgo the Downswing Sequence 6-M-1 The Pivot Train and started down with the hands? We're talking full swings here right? Or the shoulders pulling above plane and the Hands following but seeking the plane line at the same time......Shoulder work and Hand Work at the same time?
