We need something like a Addons -/ Mods folder to put scripts in.
Like you have a init.lua, wich runs the server automatic. You can then easy add player scripts, and things like that.
When im not wrong, this should already been possible. Make yourself a script with a file.find system.
Like:
data/mods/
Mods folder includes:
server(folder)
sector(folder)
galaxy(folder)
player(folder)
player.lua ( gets auto added via init.lua, this file manages the player files )
init.lua -initializes as server
....
then you need to edit the raw server.lua and include your modular system wich finds all the files in your custom folder and adds them.
This method is just like the original one, but its easier to install & updates of avorion can be applied easyly.
This is just some kind of thought of me.
