Brian,
That's the best suggestion I've heard yet. It would be simple to fabricate
a temporary sight gauge to be used while calibrating the dipstick. I
wouldn't want to drive far with it installed, but one could R&R it without
losing a lot of oil.
By the way, here's my photo of 3q. in the pan:

And here's the best photo I've got showing that the 3q. corresponds to the
FULL mark. Not quite so obvious is that the rod caps will just clear the
oil pool at that level -- avoiding the foaming and power loss that would
result if they became submerged.

It's also interesting to note that the level marks on the dipstick, because
it is not perpendicular to the oil's surface, actually indicate a range of
~+-1/8". Ain't nuthin' very accurate about all this!
All of which says that your temporary sight gauge should show FULL at
4-3/8" below the pan flange -- IMHO.
