On the topic of the future of relations between Taurians, I do think it's possible that Alaric or his successors wind up following in Ian Cameron's bloody footsteps, though that seems like a lot of other stuff has to happen first - getting the other houses on board has so many challenges, and I don't think there's much to suggest that dangling a periphery invasion is going to get them all to line up - or at least, not all are interested or care about the "southwest". And unlike the first invasion and the freedom war, the Canopians are in a really good position and the Outworlders are (however unhappily) either militarily stiffened or politically onboarded by the Ravens.
Along those lines, if strategists of all parties have learned anything (a big if for Terran and Taurian hotheads at times, to be sure) from 3067+, it's that the Davions don't actually care that much about the Taurians; indeed, the continued existence of Filtvelt might show less paranoid Taurians that the Suns realizes it might actually be better to have economically active neighbours and a stable border on the outside, especially when the Dragon and the Cappellans are such major threats, rather than have a bunch of relatively un-industrialized worlds that it's responsible for managing poorly. It seems that at the moment anyway both parts of the Taurian polity aren't all that attractive to gobble down; the more attractive it gets, the more painful it'll be to eat, too. It may be that if left to their own devices (for the foreseeable, at least) to sell and trade and deal with other local states, ALL of those small fringe actors might develop their economies enough to make them good markets for the the fine wares that khajit has the FedSuns produces. Of course, all of that assumes that the relevant decision making bodies don't go supervillain again, and obviously from an OOC perspective we want fun military storytelling - but I think there are plenty of interesting stories and campaigns to be had if 3151+ marks an upswing in the fortunes of the Taurians.
As to unit production - I can't really wrap my head around how one goes about finding out who makes what, but I went back in this thread a few pages and found a previous person's list and selected 10 mechs to form into a couple of lances + alternates.
