I'm pretty sure you can increase the number of characters, but if most of the bytes are 0s and 64s, you should probably copy from the first opponent and paste onto the new one, to be safe.
ok, i downloaded the all-star editor, i used the copy tool to make all the stages like mario's and saved what i did to the file found in the common2 folder.
now... what? i have no idea of what exactly i should do. throw it in the root of my SD card?
i am a total noob to those things, so a more precise explanation would be nice... this includes my other post about fighting 3 characters at once: i have no idea of what you just said...sorry.

well, i got some help in gamefaqs, but i am stuck.
for a test run, i simply decided to make Mario the stage 1 opponent instead of MGW. I saved the changes to the default.dat that came with the download, and copypasted the common2.pac to the System folder.
Then, i proceeed to boot the game though gecko, but when the mathc begins, there is MGW again!
any ideas of what the problem might be...?
