How good can you make your kingdom in 22 turns?

Following on from my other recent topic, Why Turtle, here:

I issue the following challenge to all "turtlers" out there. Vanilla MTW2, any faction.

Blitzers say: Breetai completed the short campaign in 8 turns, Askthepizzaguy and Sir Rethvir did it in 9. ATPG has conquered all provinces in 23 and has so far crushed all comers in PvP mode of his turtle v blitz challenge. Therefore blitzing "rules".

But some people think a turtle could win if far enough away from the blitzer at the start.

So here it is. You pick any faction. Your goal is to have the largest, most developed and richest kingdom you can possibly have, by turn 22. That is the max, no. of turns before the blitzer will get to you. Sacking is permitted. You can conquer (but you are a turtle not a blitzer, remember). You are in long campaign mode, and the settings are VH/VH.
