What they could do is turn it into generic desert-inspired mythological SF. Which, I guess, is what they did with the films and the miniseries. While I too am a fan of Lynch's original movie, I recognize its severe shortcomings compared to the source material. And don't even get me started on the miniseries where Leto II is 20-something....
