After a little further thought, although I had restored the fuse bottom lines after increasing the spinner diameter by 1/4", I was concerned that the top view might have lost its airfoil shape (assisting knife edge flight) due to the wider nose ring section. So I did a little math and felt better when I realized that my 18.5% increased fuselage width modification actually warrants a larger spinner to maintain the airfoil profile.

If the unmodified plans call for a 1-1/2" spinner and I widen the FW by 18.5%, then technically I should also be allowed to increase the spinner diameter by the same amount. Turns out 1-1/2" + 18.5% = 1.77" . Now I know why the 1-1/2" spinner just didn't feel right - not just on the G20 but also on the aircraft!

Nice little tidbit to report.
