If you could greenlight ANY GoT spinoff series, what would it be?
Mine would be a Game of Thrones twist on The Good, The Bad and The Ugly, with Bronn taking the Eastwood part (The Good), The Hound in the Eli Wallach part (The Ugly) and Karl Tanner in the Lee Van Cleef part (The Bad). It could also be new characters but very similar to those GoT characters, as Tanner is dead and the others are occupied in the current storyline.
The three of them would be on a treasure hunt against the backdrop of an epic war in Westeros. Each would have a vital part of the secret location of the treasure. Their paths would cross-cross, sometimes a couple of them would be forced to cooperate for a short time, other times they would be at odds. Characters from the main series could guest star in episodes.
