Dune: Sands of Arrakis

I have an idea for a mod. If you have read the Dune series by Frank Herbert you will know what I am talking about. Basically, I want to create a new race (I dunno how exactly I would do this) that are the Fremen. The heroes would be Paul Muad'dib, Stilgar, and Lady Jessica. I believe that modeling will be simple enough, because the only model I would need to actually create is the sandworm. Please give feedback on this idea!

If you make or get a sandworm model somehow, let us know.

Well there's the dune worm model... but that looks like nothing out of the original movie.

I was thinking that, through an intensive series of triggers and coding, I could get the worm to burrow and move while burrowed.

It'd still look like crap when it surfaced though. At the very least we'd need a model that looks like a gaping maw in the ground.
