If you look at Phil Dick's published work, he isn't faithful to his own scripts at all - the short stories and novellas weave and re-weave each others' ideas, characters and settings, and the ending and message of a story can be very different from version to version. I could comfortably imagine him reworking the DADOES plot into something just as far away from the original as Blade Runner - in fact, if anything, I find Blade Runner less radically different from the source material than some of his own reworkings. Memory is saying the two versions of Second Variety are a good example, as are the various forms of Ubik, but my books aren't currently on the same continent as me so alas I have no citations.
