CC dually lbz twin turbo zf-6 duramax..?

anyone know if any exist? im really thinking about doin a zf6 swap soon and i dont believe ive ever heard of one like this around anywhere. it would be really cool to have a one of a kind truck. plus i have a sas kit comming so it will be a soild axle crew cab dually twin turbo lbz with a zf6. sounds like a bad ass truck to me. just woundering if anyone knows of something like this thats already around or if i may be the only one :drink
