Rick, I misled you with the reference to low-angle radiation. I'm
broadly aware of how ground conductivity in the Fresnel zone works.
What I'm interested in doing is characterizing how much my signal
improves as I add radials - sort of like a distant field-strength meter.

I don't think I've ever read anything on this topic. Basically, what
I'm asking is, could ground wave to a fairly nearby Skimmer be used
as an analogue to low-angle radiation to assess the effectiveness of
radial systems on an inverted L? W3LPL is about 30 miles from me and
has a very capable Skimmer Server-based RBN node.
A radial system has nothing to do with take off angle.
Take off angle is strictly affected by ground conductivity
over a much large area than even a "big" radial field.
If you want to improve your inverted L, change it to a
top loaded vertical (IE "umbrella" wires). That will make a lot more
difference than adding radials.
