Ok, it looks like we know where this one is heading.
That being the case, my brother suggests this.
Anakin is planning on killing the Emperor almost immediately, as he so attempts to conspire with Padme ("Not too bright, though..."😉.
However, he doesn't do it, because by the time his job is done, he is now this cybernetic cripple and his great power has gone.
But instead he bides his time- and once Luke comes along, he is looking for the chance for power again...
My brother thinks that a Megalomaniac who becomes crippled in the way Anakin did and Rand has has an option to suppress his megalomania attribute as he decides to play the long term game, as his immediate loss of power makes his top-of-the-tree position untenable.
If we exercise this option, Rand can continue to play without the group having a decided leader, and with megalomania suppressed, you will not pay the animosity penalty.
I thought this could be combined with a little re-conning of Rand; character, with him being more of a Veteran Jedi than an actual Dooku-type ex-Master, and his low stas caused by accumulated injuries (at, foer example, the Rattatak arena, and now confirmed by this)
Of course, as Rand gains in experience, his megalomania will return- and by then he may be in a much better position to lead.
Meanwhile, as Rand's character changees, he gets to hack out a new niche as a custom template all of his own. The group gets to continue with Rand as their main source of Lore and other such knowledge, and still the lik by which they find new members, but not with the automatic 'must be boss' schtick.
Of course, you can always decide on another leader, but I doubt that will work- Takuan is too much of a backroom boy (who would be more likely to steal power once he is strong enough rather than get put into the firing range like that), and Galder... would probably make just as many people unhappy...
And no-one else is really suitable.
How does this sound?
