Dont worry Baron, a few days still for the bash and I realized that its impossible for me to paint an army at tabletop standard. So I am bringing a primed only army.
Sadly I do not have a Hurricanum, but the rest of your advise look good.
I may bring
3 Demys
Lots of Greatswords,
Handgunner/Bowmen
1 Cannon
I have not even read the rules or anything, so its a guess.
