The town capture idea is good. Should also be more than 1 town to spread it around a bit. Im thinking Jhelom, Britain, Magincia, Skaare Brae. These wont be missed that badly by order/neutrals espcially if Trinny will get promoted to main city.

Maybe do something like those dark knights people that were on IN1 for a while. They had 300 str but other limitations and were a huge laugh to fight against. Think they were the advance force for the second britain takeover. They were players so it was kinda pvp :p

You might want to find a way to encourage players to go order aswell. I imagine that most of XUO players will be chaos alligned so it will be very unbalanced.
Perhaps give order alligned players some pricing benefits for certain npc services or create gm supported order guilds instead of chaos ones.

i dunno how ur order/chaos guilds were, but on xuo, even orders ganked. only thing was if u were order and saw a chaos on a guarded town, u could attack each other and loot in the city without being guardskilled
