Opinions requested

I've been thinking, would you guys be ok with it if another writer took the series original characters, like Mumbo, from this show and put them in another show, maybe even exploring their backstory? The fun part about the series original characters is that we can make up backstories for them, and I mean even if another show did their backstory that doesn't mean you couldn't make a different one. But at the same time, those characters are the staff's ideas, would it even be right to use them in a different show?
