Different stages and bosses for different characters

Example : Goku and Vegeta will have Kid Buu as final boss while Kid Buu is the other way around.There is a code on LFE that allows you to do this.There are also codes that can make you create more than 5 stages.Go and check it

I'm not really focusing on the stage mode yet considering I don't have enough characters for a specific saga completed to even make it happen.

Can you atleast do something about survival mode?That thing needs to be optimized a bit.Before a boss,I keep fighting android saga vegeta and sometimes,he dissapears and after 40 battles,the battles keep skipping and skipping.Plus I have some backgrounds of stages from Super Butoden series.You can make a new stage by making an edit of lee on road.Remember the mountain road where Vegeta and C18 fought?I have a background of that stage and it looks great.You just have to take off the dark background and the moon off of lee on road and replace it with that background.
