Winning Tukayyid would be a rather impressive feat for the player to do single-handedly. Even if the Jaguars are allowed to complete their objective in this game's version of the Battle of Tukayyid, I expect the Clans will be halted regardless, because I think more than two Clans (the other being the Wolves, of course) will be required to succeed for a Clan Tukayyid victory to happen.
Winning Luthien is definitely on the table, though. However, it's possible the narrative will put us somewhere else entirely while that's happening; if (admittedly a big "if") there's a Clan update to Mercenaries that releases alongside this game, we could wind up defending Luthien instead, as the Cavaliers.
In any case, we're looking at a linear campaign that seems structured more like most campaigns we've seen that didn't carry the Mercenaries title, so I don't think there's going to be any randomly generated content, at least not until postgame if there is one.
