So the annoying thing about Lockdown is the inability to play with friends/against guild members. So what if we added the SK equivalent of the Halo custom game? The idea is that instead of random matchmaking, you could form your own party with guild members and friends through a sort of lobby system.
To avoid farming and such, the Krogmo coin rewards could just be removed for the "custom game" matches, and the cost per game is reduced to 50 cr/player or something (to balance a lack of reward). There should also be no rank increases while playing a custom game, just like how playing custom games in Halo won't increase your rank (by any substantial amount, at least).
