OK, I can't say I have ever played Orcs yet but I do like the idea of it for ****s and giggles and have the new Codex so, just as a thought, how does this sound for a new Orc Deathstar Unit?
1 x Stompa with Grot Riggers for that super hard, worry the crap out of the enemy, 20 model transport weighing in at 800 pts.
Add to this 10 x Meganobz (just about as they are bulky) all with 2 wounds, 3 attacks (armed with 2 Killsaws each - S x2, AP 2, Armourbane, Specialist Weapons) and that lovely 2+ Sv for a further 500 pts excluding any. boss poles you throw in (each model can have 1 at 5 pts each).
Ok, yes that is an eye watering £222 in English money if bought direct from GW but ask yourself, are you worth it? ;-)
