Trying to rewrite ship launch result

[AgentBlac1]

Hello

I've been trying to make an endgame expansion mod, which begins with an alternate result of launching a built endgame ship, instead taking the pawns that are inside of the cryosleep caskets to another map(not planet, just map).

I've seen a couple mods (setup camp, marsx(kinda)) that showcase the spawning of previously non-existent maps from normally vanilla circumstances, like the camp mod spawns new maps every time the "set up camp" button is pressed on the world map.

I was wondering if anyone could help me with taking this concept and attaching it to the "launch ship button" that results in the game ending in vanilla.

Any and all help is greatly appreciated Thanks in advance.
