It's pretty much the approach that incarnations of every franchise have taken when drawing from other incarnations. I keep talking about this in various threads because it's a recent interest, but the Superman comics of the early 1940s drew elements from both the radio series (Jimmy Olsen, Perry White, kryptonite) and the newspaper comic strip (the Daily Planet) while disregarding other aspects of them (e.g. having Superman be a public figure rather than the clandestine type he was in the pre-WWII radio series, or having Jimmy be red-haired instead of blond). And the '90s Batman comics drew Harley Quinn and Renee Montoya from Batman: The Animated Series, as well as rebuilding Gotham City to echo Anton Furst's designs from the Tim Burton movies, while still being distinct from those continuities.
