You ar right: my proposal is weird and crazy, but there is a large
advantage: it is testable:

If my proposal for the Planetary (Earth) gravitational drag of the
Lightspeed has a realistic base, as mentioned below, then all GPS
signal readings taken by other satellites should account for such an
effect.

....
Outside these areas, the "Earth gravitational drag effect" should be
incorporated into the GPS-reading calculations. This should be the
case e.g. for so called LEO "GPS-occultations" skimming the Earth
atmosphere.

You are neglecting the fact that the atmosphere is an ionized dielectric
material with various degrees of ionization.
The degree of ionization is influenced by solar radiation.
The nearer the GPS is to the horizon, the more variations that will be seen
in signal propagation DUE TO those factors.

You will see those variations as 'signal' in your experiment but those
variations are 'noise', as far as what you want to test.
Unfortunately, the 'noise' is correlated with the earths motion around the
sun, in the same way as the signals that you are searching for.

Absent a LOT more data than you have any means of collecting (the exact
ionization levels at each altitude for each volume of atmosphere along the
path that you are studying, along with any possible multi-path propagation
paths), you have no hope of digging a signal out of the noise.

Hello BZ,
For my SIMPLE GPS EXPERIMENT on Earth at a moutain summit measuring
the possible diurnal distance variation of low horizon (Earth
skimming) GPS signals, you will be probably right.
However it is worth to try isn't it?.
At the other side of the test, between GPS and lEO or stll better High
ALTITUDE SATELLITES (FAR OUTSIDE THE ATHMOSPHER) the effect should be
multiplied, if the proposed cigar shaped LASOF area has a decreasing
gravitational drag-effect at these levels.
