Context: As a personal challenge, inspired by an indie tabletop card I once saw, i decided to mix a few genres with each other, mostly focusing on unusual/rarely mixed combinations of genres/settings. Things like Gothic Western (part of the weird west genre), Eldritch and epics (like the odyssey), and cyberpunk with posapocaliptic. So far, no problems, but then I decided to try mixing something with pirates. Went on another reddit to ask about that. In the en, I landed on dieselpunk and sky pirates. So far, so good.
Then, I started researching. Pirates are not a genre per saying but a mix of two other types (adventure and swashbuckling), and worst of all, dieselpunk doesn't have a lot of media (original ones, not by assimilation like Mad Max, apparently?), and it didn't help that the only idea i managed to make for a protagonist is a guy who doesn't use blades and guns (modern guns being another key element for dieselpunk story settings), but who didn't even fly a plane (he was going to pilot the ship, but I'm not sure anymore).
What i do have (that I'm sure to use it) is this:
Lost treasure islands known by the families of legendary pirates inspired by the flying gang (blackboard, horningold, rackhan, Mary read, Anne bonnet, etc).
Zeppelin like sky ships or planes.
Gun swords and other melee weapons (RWBY style)
The ground floor is a volcanic wasteland of death.
The first age of piracy came after a long war, and many pirates were members of the navy/veterans.
Raids are either done by boarding or dogfighting in plane looking vehicles (I'm thinking those bikes from the TV series Storm Hawks).
The protagonist's name is Rosso Read (yes, I know the joke/reference).
The protagonist meets his first mate like Luffy meet Coby, but in this case, the "coby" sticks with the protagonist.
Humans are more common, but I might make new fantastical (or use the less known) races. Only one else is of the first mate, which is German rat people called Maus (yes, i know it's literally the same word in german).
I'm not looking for any help writing or someone to write it for me (I know the rules), just your thoughts and opinions on this crazy wacky idea would be nice and, maybe, just what I need to unclog my mind.
