Beforus ancestor episode and or movie. Good or bad idea?

This will almost definitly never happen. But its something ive been thinking about. I think a episode or movie showing the lives of the beforus ancestors might be cool. Somewhere before chapter 5. A new viewer would see what the charicters are like as adults in a less volatile society. So when they see the same charicters as kids idolizing manipulation, disabling eachother and murdering eachother etc. There is a bit of an oh shit moment and maybe a bit of intrigue as to how whats going on is even possible. I know this might be sacrificing alot of mystery though. Outside of that it might just be a cool standalone movie to release whenever. If they ever want to do a theatrical release. Im assuming there is probably a desire to leave alot of the lives of the beforus ancestors up to fan interpretation. But i was thinking since this would technically only apply to world of show it might be ok. Curious as to what other people think.
