I might test that later today. I'm guessing it has Halloween Town's Antiform appearance and Xigbars guns or something? It's easier to test when you know what results you want.
I would save Demyx, because if he had the choice he wouldn't be in the Organization. I would consider Xion, but she died for the better, because if she didn't, Roxas probably would have been killed. Not much of a point to saving Roxas, because he died happily.
It will usually work no matter what order unless there is a joker. Joker must be on top of the lines you want jokered, and if you're not jokering all the codes, you'll have to put the ones you want jokered inside the area that is being jokered (Wow, I can really over complicate things).
Instructions: Replace the ???? with whoever you want to fight. Then, while going into the Sephy battle (or another room) hold L1. Do not regain health in any way until you get to the battle. To exit the battle, cure in some way.
Just for fun: Use full party and make both allies bosses. Yay! They will be defeatable though.

Most people like the labels, so I just copied and pasted. Never was tested.
Ok, I added a little and btw, it's for Wisdom, and your Keyblade used should be either Kingdom Key, or Oathkeeper.

If it works, all magic should be level 3, you should have no MP charge, Wisdom should look like Final, and your magic should be Rainbow colored.
Alright! I've finished my first custom form (after canceling my actual first)

Would it work if you went to the room where a boss battle you used a room mod at the same time? So the flag wouldn't change but it would relocate the battle? Cuz that's how they did the Sephy battle relocation in KHI right?
