I'm not sure a faithful adaptation of Do Androids Dream of Electric Sheep? would make for a great movie, but it would certainly be quite a bit different than Blade Runner. Really, there are enough ideas in the Dick novel that you could produce a dozen wildly different adaptations using the book as a launching pad.
I think that an HBO limited series of Do Androids could really be awesome. Or even an ongoing series with the first season being an adaptation of the novel and subsequent seasons different stories set in the same world.
