DO JOB SYSTEMS WORK WITH MORE THAN 4 CHARACTERS

five guitaromancers and a jedi

If all the characters have the potential to be the same then I don't understand why you'd let the player pick their characters. It is not a meaningful choice, the only thing they are choosing is their character's graphic.

If they can swap party members mid-battle then I apologize and it makes more sense. Since that means the player is really using everyone, not just picking four of them.

If the characters are not noticeably unique in battle, and the player can only use a limited number of them, the only other reason to give them a character choice is if the player's choice of party members has some other sort of meaningful effect on the game outside of combat. For example, if the game has an exceptionally high amount of inter-character dialogue between your party members (as in several hours worth), which would make their personalities an important choice. Or, uh, if you're making a hentai game, which would make their graphics an important choice.

sith =/= jedi

because there is no argument, the sith are an order unto themselves both similar and separate to the jedi

good analogy: christianity, judaism and islam are all abrahamic but it doesn't make them the same practice

it is useless to resist

the simplest argument is: i question the canonicity of star wars characters rockin' out
