As I wrote above, it is a Might-Be-scenario, less be "Wishful-Thinking".
It's absolutely wishful thinking at this point, as we know that TPTB have no current plans for the Home Clans for the foreseeable future. T
Why I see a conflict between Wolves and Horses coming? Because Alaric Ward would never accept anything on equal footing with himself and his Wolves. Everybodey must submit. No "First among Equals", but only "First".
The Horses did resist him on Terra, something he will never forget.
Again, Alaric has a laundry list of much more immediate concerns, and the Horses certainly aren't on that list. We've seen no indication that he intends to punish them, and the Horses themselves have made it clear that they also don't particularly want to pursue a conflict with Alaric. If anything, Alaric was incredibly dismissive of them and seemed more than content to ignore them into oblivion instead of validating them.
Further he will never forget that the Horses invaded the Wolf Occupation Zone during the WoR and captured many star systems of the. They killed Vlad Ward.
We haven't seen any indication that the Wolves are still harboring a grudge over those events this many decades later. Not to say that they aren't, of course, because we all know how factions in BattleTech are about holding grudges, LOL.
Making an example of the Horses will strenghten the ilClan standing among the other Clans.
It will be many years before Alaric is even remotely in a position to do something about the Horses.
So what if this might happen and the Horses are losing the war with grevious losses, getting close to be annihilated? But they might remember of this "Auld Alliance", do you not think they might give a try?
Not really, no. I don't see the Horses going to an enemy to try to fight off another enemy.
Given the Horses novel and Without Question they are described as be ing the most conservative Clan in the Inner Sphere.
I disagree with that assessment. The Horses are certainly not a conservative Clan by any stretch. They have healthy inter-caste cooperation (despite the Horses novel's blatant mischaracterization of things, the Horses have always had this going for them and it was shown as recently as "A Rending of Falcons"), are willing to deal with Inner Sphere powers on a mercantile level, are willing to embrace new technologies (QuadVees, TankWarriors, the continued use of ProtoMechs, etc.)... I just don't think that's an applicable term for the Horses.
