Colin Weaver produced the genetic equivalent of this, a hypo super pastel black pastel lesser platinum. I know pastel isn't recessive, but I figured since it was the super form it is equivalent. Here is the thread about it:

The problem with producing snakes with so many different morphs in them is that it gets harder and harder to know which genes are or are not present in the snake. The thread Derek (dr del) linked to explains that somewhat. Also, if you follow corns, or read about Rich Z's retirement, one thing he talked about in regards to selling his collection was how could he even put a price tag on a snake when he didn't even know what genes it carried?
A second problem with producing snakes with many different morphs in them is that it will get harder and harder to find combos that are exciting and different. Think about how many different ways there are to get a white or mostly white snake. It (most likely, although sometimes things react in unexpected ways) won't be very interesting to create an ivory snow BEL BlkEL. That pretty much eliminates any combination of those for creating an exciting new look. Yes, they would be genetic power houses, but snakes need to have visual appeal for the pet market as well. And while pet owners will go ga-ga over a white snake, they aren't going to pay more just because it contains more genes but looks basically the same.
And finally there is the obvious problem of the insanely low odds and/or years and years of work to produce some of the theoretically possible combos.
As far as whether or not a snake could theoretically have all the genes, I'd say yes. So far breeding trials indicate that the vast majority of morphs are on different loci, and that means a snake could theoretically have genes for all of them.
