Relocate twilight thorn battle to more stable location (not a code request)

I didn't know where else to ask this so if this is not the place for this please move to the proper section...

So I want to relocate the twilight thorn battle to a more stable location but the only difference is I want to fight the twilight thorn as sora? So if it's possible I wanted to know the most stable location to fight the twilight thorn as sora. If there is such a location that is!

 

Not super helpful, I'll admit, but what about modding the Twilight Thorn into a fight in the Colosseum? Its original arena and the fighting area in the Colosseum fights are about the same in size and you could even make it look "official" by modding the text to announce the round.

I've seen people with modded rounds before but I personally don't know how to go about it.

 

I love this idea, I just might do that!
