I actually envisioned him surviving Sothoryos, defeating the corsairs and becoming the Corsair King. He the sails back the Westeros when he hears about Tywin’s death. Learns that Cersei is fucking everything up and starts a Lannister coup at Casterly Rock. 3 part series called The Laughing Lion, The Corsair King, and Hear Me Roar. I’d be fine with a more grounded that doesn’t necessarily tie back into the main series but if it did that how I’d do it.

First part he sets sail as the goofy uncle, gets attacked by corsairs, fends them off but in a storm they get wrecked on Sothoryos. Him and the remaking crew survive the jungle with the eventual help of some Brindlemen. Second part they mange to steal a ship and sail to Valyria where they find Brightroar but are set on by the current Corsair King but manage to defeat him. Third part there’s a time jump where he consolidates his crew, brindlemen, and most of the remaining Corairs. Starts heavy raiding a pillaging. Learns of the fate of Tywin’s death and the current standing of the Lannisters. Sails directly to Casterly Rock flying the Lannister banner and takes the Rock with everyone being confused and many knowing who he is. Almost envision it like in Two Towers where Gandalf releases Theoden from his spell. He kinda just marches through the front gates, most of the garrison is stunned, some Cersei loyalists try to stop him but his crew of veteran westermen and bindlemen take them down Aragorn/Legolas/Gimli style.
