True and Nolan mentioned, around the time of BB, blockbusters like THE EMPIRE STRIKES BACK, BLADE RUNNER, RAIDERS OF THE LOST ARK, Donner's SUPERMAN even THE SPY WHO LOVED ME as examples of fantastical movies that still had a sense of reality to them compared to their many modern counterparts(the films of Michael Bay for example).
Nolan doesn't dislike fantasy concepts in his own work (THE PRESTIGE) so it wouldn't surprise me if he chose to add the more 'supernatural' elements of the mythology to a future entry, and here's the thing, make it work so audiences aren't rolling their eyes.
