If you have an insane opponent, or a really friendly one, he may let you use Shrike's rules in the BA codex in exchange for Red Thirst or something.
If you want to use codex chapter, Shrike w/ assault terminators or vanguard vets is usually how I run my lists. Use scouts to fill up your troops slots and vary between land speeder storms and assault squads for your fast attack.
Just stay away from heavy vehicles like land raiders, vindicators and predators and I think you'll be able to pull off a fluffy list.
