Honestly I like the idea of the Wolverines becoming the boogeymen of the Clans after the 3150's no matter which Clan takes Terra. Imagine if each Clan gets hit with terrorist attacks by both guerillas and Battlemechs all identifying themselves as the Wolverines. Destroying depots, conducting sabotage, assassinations. Something to drive every Clan crazy trying to track down and destroy.
Sort of like this one movie I enjoy...
I do not believe the Wolverines will EVER make a reappearance.
There is simply no way anyone could ever create a story or scenario that would please everyone. Or a majority. Or even a majority of a minority.
There is simply too much contradictory information about them and everyone has their favourite theory.
I've made no secret of mine....McEvedy made a power grab. McEvedy failed. McEvedy ran.
Maybe she did it for good reasons. Maybe selfish. But that story fits in with most of the available information while BoI can be portrayed as canon...in that it is a canon depiction of the Society story, the book they released to stir up the lower castes. It may even have some degree of truth in it.
But generally speaking, if I have to choose which information is going to be declared "false", I'm going to choose to invalidate the least amount of information.
Not to mention, I believe the failed coup idea gives the Wolverines far more personality and story potential.
But others are going to feel differently.
As for THIS specific idea....first, a bogeyman for the Clans doesn't require the Wolverines. As stated, the Homeworld Clans would work just as well, and bring in already developed factions that need exposure.
Secondly, this storyline has arguably already been used. The Bears were duped into the Jihad by linking them with the Wolverines. A false flag operation would work just as well as the real thing, but has been used.
