I would also add that Concord also messed with base game mechanics, most notably with Sensor Strength and Profile, which was a bigger no-no.
But I'm not necroing just for that:
Someone on unofficial discord made a bootleg version of this called Postmodern Carriers.
Main differences are:
1) No need for Concord, at the cost of everything Concord dependent being cut;
2) Several Hullmods that were previously removed by Sutopia are now back;
3) Changes to Fighter auto-docking logic;
4) LunaLib dependence, mostly for point 3 above.
EDIT: Just realized they made
a thread for it here, sorry.
