Will CoC d20 be a bridge to classless/levelless D&D?

[Desdichado]

Lovecraft never envisioned a mythos. (Let alone a Mythos.) he and his friends wrote a bunch of stories, some of them with tongue firmly planted in cheek (see Luveh-Keraph, High Priest of Bast, for instance) and used common elements in many of those stories. There was no attempt at any sort of coherent mythology. And the futility-of-human-existence meter varies wildly form author to author, and even among stories by the same author (Nyarlathotep and company seem almost envious of humanity in parts of The Dream Quest of Unknown Kadath, for instance.)

I agree and disagree. I've never considered The Dream-quest of Unknown Kadath to be part of the mythos, as it is an obviously Dunsany-inspired work that has little in common with many of the other stories. Similarly, some stories such as The Case of Charles Dexter Ward seem to have no connection whatsoever with any form of "Cthulhu-ness." However, there are others that fit really well with the emerging embryo of a mythos in stories like At the Mountains of Madness and others that have similar themes, tones and further build on ideas of a mythos per se. Actually, perhaps there are two sets of mythos: the Dagon/Innsmouth stuff and the other stuff spelled out in At the Mountains of Madness and others. The two really have very little in common with each other, except for occasionally shared names.
