I’d go with the Marauder and Banshee. More PPCs (and a Gauss Rifle) fit that lance better than adding an LRM-heavy mech like the Archer. I’d use some combination of Archer, Victor, and Axman to round out the new command lance. You could make the whole group short-range bodyguards (VTR-9B, AXM-1N), or add indirect fire support (Archer, AXM-2N), or mix in some more direct fire (VTR-9K), depending on your vision for the command lance.
