I really loved playing warband tournaments in fantasy battles, i was wondering if there was a 40k equivalent for it?

warbands were 150 start 500 max games played with charater archtypes (personalities that offer bonuses) for independent characters

played on 4x4 tables with lots of terrain

no more then 3 independant charaters with stats that can exceed 3 wounds

charater injury charts for when they are downed in a game

the loss of units destroyed in game with a d6 roll 1-2 it dies 3-6 it lives

an exp system that is determined by the difference in army points and a 3 tier victory defeat scale

Anything like this for 40K? i would very well love to know, its what got me and alot of my buds into warhammer.
