Cameo Fantasy III

Freya is currently replacing either Phumbaba or DoomGaze.
The idea for Phumbaba being that Freya was Odin's right-hand commander who basically abused Terra (while she was under Odin's control) about as much as Kefka, and also was responsible for killing Millenia (General Leo's replacement). Or something like that.
The idea behind replacing DoomGaze is that Freya flies~!
I really like the idea of a boss fight with Silmeria and Brahams, but I'm not sure where I would fit that in... I have a list of undecided bossfights at the top of the first post... which one do you think might work? Lenneth is replacing Celes, and there's not a lot of Celes-specific boss fights, despite her being a main character.

In the WOR, there's this quest to recruit Sabin in which you've got to save the little boy from the crumbling house with only Celes. What do you think if you make this "boy" a little girl named Alicia, that tried to hide herself there from Hrist by guidance of silmeria?? When Lenneth finds Alicia inside the house, she flees when sensing Hrist, and promises to meet lenneth once again.

The party may find Alicia somewhere inside odin's castle ruins (war of the magi) and when they try to talk to her, she starts a fight as silmeria...and I ran out of ideas

It may be easy to do the first part in LE, changing the boy sprite into the girl, and removing the boy's sprite from Tzen after the house crumbles to be consistent with the changes.

About the event editing for this... If I remember well, the kid's NPC sprite is coded to follow celes, once you talk to him. You can just have the NPC run and disappear, and edit some of the dialogue for her mom outside. Tell her mom that her daughter fled to another place or something...
I haven't thought about creating the event for the boss battle inside odin's castle..., but let me know what you think.
