That said, having seperate polities as member states of a Wolf-Led Star League would be better than having six thrones himself. For one, should Alaric die, member states might remain member states, while those thrones could slip away. Further, uniting various parties into a Wolf-Led Star League would put pressure on the parties not inclined to join.
Were I the Khan, and things go down roughly as I imagine they will, we'll have a Post-Mongol Clan Jade Falcon, hurting from failure to stop the Wolf ilClanship AND from Hell's Horses preying on their OZ. Plus, focusing on the Wolves has allowed the Lyrans a moment to breathe. We'll have a Federated Suns struggling for it's survival against the Capellans and the Combine, neither of whom is a friend of ours. Plus the FS has a legitimate grievance with the Snow Ravens. So, I would offer to Clan Jade Falcon "Acknowledge our ilClanship and join our Star League. In return we will offer you the league's protection from being absorbed by the Horses and help you get back on your feet" and similarly we will reach out to the Federated Suns and offer our support against the Combine and Confederation, who are not member-states (and frankly, I can lay a significant amount of the blame for the succession wars at the combine's feet, as it was a Kurita who refused to acknowledge Davion as the successor, so there's cause for a grudge there too) in return for participating in our Star League. I am reasonably sure that the Sea Foxes will see the profit in participation, and through them we might be able to get the remnants of the cat clans to acknowledge us. Particularly if it means a chance to rebuild themselves as clans.
The Bears? Eh, the bears are going to do whatever the bears want to do. It'd be nice to see if we could entice them to tear into the Combine, but I'm not counting on it. a Bear/Wolf alliance is almost too much a fedcom-esque I Win Button. I'd be happy with a token acknowledgement and leave the Bears to do whatever they're content doing.
The Horses? Well, the Skinwalker hints at a possible Wolf/Horse Collaboration. But there is that bad blood from the late 3060s and Reaving Eras. I don't know how to call that one.
The Ravens? It'd be nice to have them. Maybe the FS joining the Star League would pressure them if they're reluctant.
The FWL could probably be brought into the fold with Sea Fox/Preserve Cat help. We've successfully dealt with them before, and we could cede some systems back as an incentive.
The Lyrans might see sense in participating if we cede some Empire worlds back and promise that participation means survival and a chance to engage in civilized trials to regain territory. Or they might resist and make a target of themselves.
I would say the Combine and the Confederation should be struck hard, humbled, made example of. Once they're bloodied, then give them the option of capitulating and acknowledging our League to end the pain. Offering the Falcons a chance to tear into the Confederation, and giving them a chance to gain territory that isn't surrounded by the Horses and the Lyrans might be welcome. Or perhaps the Bears can be tempted to take the Confederation into the fold the way they have Rasalhague, since half of their founders ancestry was Rasalhaguian and the other half was Capellan. Facilitating that might be a way to get the bears' enthusiastic participation in the league.
