What effect would installing a 10K resistor in place of the 100K in R21 (connects between Power pot and Gate terminal on the MOSFET) position have on VRM operation? Would the VRM operate, but without proper power scaling?

The 100K/220K set up a voltage divider to determine the lower limit. Using 10K would negate that.
Why would you? If you want to lower the bottom limit, drop the 220K to 100K

Mistakenly added 10K in place of 100K in first build. Am double checking w/ friend who purchased it. He really likes amp even with the 10K, but I'm sure with the proper 100k in position , it will add an extra dimension he didn't know was missing :!:
