100 mile update:
I ended up making two modifications that allow me to shift all gears between 50/34 front and 32/11 rear. I have experience adjusting FD with 53/39 with 11/23, but the wide range compact gearing did require bending the rear of the FD cage for a slightly wider exit for silent running.
1) This was a new bike build with a nice and shiny braze-on deraileur. The new "D" metal block and lock washer that came with the front deraileur, even when tightened down, slipped after many shifts. The FD cage would end up skewed after many shifts and bumps. I did not want to bend the hanger to match the saddle point, so I roughed up the "D" block with sandpaper which stopped the slipping.
2) I kept the widened rear cage but removed the spacer and longer screw and just bent the screw bracket on the front cage. This kept a low, flat bottom rear cage.
