Doctrinally
Until we get someone who can write better wolves than those presented in HotW, Alaric's Wolf default doctrine is "GO FASTER. SPEED LIFE." Sure, Wolves made the crucible. As something to cover supply trains. Not as a mech for offensive operations. Wolf doctrine has no use for a 2/3 chunkerbus.
Like said earlier: Hell's Horses horde clusters could absolutely use a superheavy tripod. But they have the correct culture, doctrine, and pool of available troops to crew them. Wolves have none of that.
Essentially that's what I concluded as well if we go by the how novels have been written what has been written so far about the Clans sourcebooks wise, but were not completely update now about that.
What it comes down to it is the superheavy are slow, tripods can eeek along bit faster due only paying for 1 turn facing, vs multiple turn facings. Thus you save limited movement speed being eaten up by turning.
Hell's Horses do have the right kind possible training to create the crews/people to operate Superheavy that requires a crew 3 people. However, Hell's Horses aren't your Dad's horses, they've gone from combined arms to FAST combined arms with preference move quick on an opponent and objectives with it's frontline forces. Superheavies are NOT that. Garrison Cluster for sure, possible secondary roles as a defense, slow assault, breaking sieges maybe, big honking artillery piece, freeing up smaller assets and their possible omnipod spaces for more direct weapons attacks. Certainly as a Command Unit to provide initiative bonuses for friendly units have jump on their opponents.
All and all, Its hard to say if it work. Outsider of game in the real world, It's up to the BT developers if they can get money Superheavies and has the community's backing for it. They side lined ProtoMechs, LAMs, Warships, etc because focus on just BattleMechs and with sprinkling of combat vehicles.
One thing Superheavy BattleMech do have is their BIG MECHS, everyone like big bots. So maybe Solaris arena match machine with improve targeting for melee attacks than difficulties of swinging light mech size mace at someone negated.
