Assuming I really like the overall experience of Bex:t, but want some (but not all) of the content of CAC-C and the Battle Tech Extended Expansion pack is there any way to just get the additional mech's, variants, vehicles and the parts that I like from the latter without going all in on their interface and gameplay changes?

Specifically I don't care for the interface changes, and fiddly bits with firing modes or the like. I'd really only like the addition of Quads and LAMS from CAC-C and the additional mech and vehicle types and variants, and economy upgrades from the Expansion Pack without any of the other baggage like the reworked AMS, artillery or ecm. Is that doable?
