Due to the fact that we know the lunar profile very well it can be intersting to try the beads observation from the center line. In the past we travel to the north and south edge. Sure the libration effects are much bigger in the longitute than in the latidute and the re-calculation would be more difficult.
Yes, in principle, it's possible, and the many near central line observations of past eclipses might also be used. Since LRO is in a polar orbit, the LRO lunar limb data are still better at the poles, but the mission has gone on long enough to cover the equatorial regions quite well, also. Kaguya was not in orbit long enough to do that. Anyway, it will be interesting to compare results at the 2017 Aug. eclipse, from both near the limits and from near the center.
I guess if I check out your papers that there are many amateurs and professionals along the eclipse path doing similar measurements like you do.
Maybe asking via a popular website (like Sky and Telescope) or solar mailing list for support to your project would help, definitely more than via Research Gate.
I am an amateur astronomer who will also travel to see the eclipse but will not engage myself in imaging it.
