Randomizer?

Would it be at all possible to make a program that shuffles around the game data?
Specifically I'm thinking of:

• Scene order (eg you start in the sor2 bar, going up takes you to the sor3 club, going right takes you to the underground fight club)
  
• Enemies/Bosses (eg galsia becomes big ben)
  
• Items (weapons/healing/etc)
  
• Completely random enemy/item placement (could be messy)
  
• Music (you can do this already by swapping files around)

I'd be more than happy to make the program myself, but I have no idea what kind of data formats the game uses.
Also, if modifying the game's data pack is too complicated, then perhaps we could use the original files to make an SoRMaker mod that plays in a random order?

A randomizer mode would be great for Survival tbf. That's something SOR4's Mr X Nightmare did quite well.
