You could do it with the Saxons in VI, The Will of the Thane, you could do it with Britain in the (original) Napoleonic mod, The Will of Parliament, you could do it with HRE in MTW or MTW2, The Will of the Electors, or Venice in MTW2. Lots of potential options.

A lot depends on how MTW2 in implemented, eg how the missions from your elders & guilds work.

DDW, that was some impressive work, a full stack of macedonian Phalangites with +7 attack/defence is not to be sneezed at!
