Playing Dwarves as Chaos Dwarves

I downloaded the GT Chaos Dwarf army book, and i must say its amazingly well written and i like the units a lot also. I have Dwarf army that i have yet to use, and was thinking about using them as Chaos Dwarves. What do you guys think ?

Planing on using the Organ gun or the 2 cannons from the BFSP set and convert them a bit to Death Rockets.
Still thinking on what im gonna use as a EarthShaker canon, maybe the Dwarf Grudge Thrower (Stone thrower) ?
Got me a sorcerer on a Lamatzu from a trade.
Dont think i'll be getting any BullCentaurs since they suck with the new calv rules.

I know we were talking on another post about unoficial books, so not sure if it would be ok to use the GT book for tournaments/campaings or use the Old "OLD!" GW list.

I have seen hell cannon conversions. Manic made a great Deathrocket thing, oh you could use i think its called the Thunderbelly Cannon from reaper. I have the model i will send you a pic of it. it was like 12 dollars. it could of an earth shaker

also you could use an empire mortar as the base for a conversion

Mortars make good earthshakers

agree but work needs to be done
