Assuming you do 3 rounds of battle ?
1 round:
Meeting engagement.
As I suggested earlier, have players make a basic armylist (eg. 1250 pts) and 3x 250 pts sideboard. Nominate 2 parts of sideboard as Vanguard.
At start of game only Van is placed on table in opposite corners, from start of 2de turn allow players to deploy additional Brigades (one on the short side and one on the long side from the perspective of the corner of original set-up.
2 round:
1st round losers play a defend you homes game.
Played in the LENGTH of the table.
Place an area (30x30 cm) of buildings or other suitable markers one third in from a short edge of the table. Defender can opt to play his BASE list (1250 pts) and have one sideboard as reserves. To compensate any or all of his infantry and artillery/machines can start the game in defended position (use markers as appropriate). Defenders units in the "village" are always considered to be defended, except when falling back from combat. Visibility in village is deemed to be 8 cm, Cavalry/flyers CAn enter and fight in village but will NOT be able to "disengage"
Attacker plays full list. Defender deploy first, attacker deploy second and go first. reserves can enter on any table edge automatically AFTER and attackers unit enters/attacks the "village".
Attacker (auto) wins when Defender has no units in the village and attacker has at least one full unit in. Any and all units (of both sides) in the village at the end of battle give appropriate VP to their OWNING player.
Round 3:
Match up winners/losers of round 1&2 and replay the round 2 scenario with players in opposite roles as 2de round.
Standard battle for the other combinations, use 1-3 objectives on the table for extra VP.
BTW... assuming event in (or near) Antwerp and a workable date, I might come over and help out (as neutral player, or natural disaster

)
