I find it fun to see what is available on the MUL as well!
The thing you can't get from the MUL is how rare a mech may be. I think the Orion and the Bushwacker would both be pretty rare mechs during the Jihad, and especially by the end. Come to think of it, both the Banshee and the Bushwacker were Lyran manufactured, so as the Jihad went on, it would be difficult to get replacement parts for them.
If you wanted to go with Davion produced mechs that might have an easier time getting parts as the Jihad progressed, you could replace:
Banshee with: Devastator, Templar, Longbow, Nightstar, maybe a Marauder II 4S if you really want a Steiner design as your lead mech.
Bushwacker with: Enforcer III (any), Shadow Hawk 5D, Rifleman 8D, Jager (DIII or 7F)
Orion is a great flavor mech and maybe keep it for variety's sake? If not
Lastly, and probably least relevant: I have god awful luck with the 8D and 9D Wolverines. Davion mechs to be sure, but those RAC-2s just don't do the justice when for 2 tons you could stick a 5 on there. That, and mine seem to always get a TAC Gyro or Engine crit early on. If the goal of strike lance is to move into close combat, you might be better off with the lower tech Shadow Hawk 5D because it lacks the XL engine and is a decent zombie with Case.
Just some ideas.
Orion is a great flavor mech but would be super rare in the Suns IMO.
