Snowy: it's so GREAT to have your analytic voice around here (it scares nowadays),=) but just you know : a Discovery Channel interviewed zoologist openly commented that the producer of TLK are completely studyless of the lion prides. He said that in real lions, such insurrection as Scar did to his brother is the most improbable since single male lions without their coalition will seldomly success in defending their pride from forces with two or more male lions. So, anyway, if the makers of TLK ever considered these unsolved questions, it has the least chance that they think it in realistic way. Not a obscuration to your theory though.
Hope you come here more often
