I've seen some people saying the fake!Daeron plot was actually a smart idea from Ryan Condal. But guys don't be giving him too much praise because this idea is copied straight from the ASOIAF novels and the Game of Thrones tv series.
In Game of Thrones and the novels, Sansa dyes her hair darker so no one will recognize her red hair and she pretends to be Petyr's bastard daughter.
And switching out the real person with an imposter isn't an unique idea either.
In the ASOIAF novels, no one knows what Arya looks like so they force Jeyne Poole to pretend to be her and marry her off to Ramsay and only Theon recognizes who Jeyne is.
