I could see the Dragoons, and/or the Warden Wolves, becoming mainline Clan Wolf or IlClan galaxies. It would kept the legacy while getting a bit of faction consolidation, which wouldn't be a terrible thing.
Come to think of it...
[Alaric] <seizes Terra>
[Clan Wolf] Yay! Clan Wolf is the ilKhan!
[Clan Wolf-in-Exile] We‘re ilClan, too!
[Wolf's Dragoons] ...and we'll be your ilMercs, because we're Clan Wolf, too!
[Steel Wolves veterans] So are we!
[Wolf Hunters] <wave hands frantically>
[Snord's Irregulars]
My wife's ilClan, too! Reporting back from detached duty for ilMercship.
[House Steiner] Given Alaric's maternal heritage, that makes us the ilHouse then. Long live our Third League First Lord ilKhan Alaric Steiner-Ward-Wolf!
[House Davion] <raises hand> *cough cough*
[Malvina] Seeing how my Jade Falcons pwned the Wolves in the Refusal War and absorbed them, that ilClan title totally belongs to the Jade Falcons. And I've got the WarShips and nukes to prove it. Dare me.
[Fidelis] Actually, Clan Smoke Jaguar kinda sorta combat-landed on Terra first with Stone back in the Jihad. You guys are half a century late.
[The Blood/Wolverine Cabal/ComStar/Word of Blake] <snicker>
I think I'm going to like the ilClan era. :)
