What are some spin off ideas for the helluverse

The series creator said she hope to get at least 5 season for hazbin hotel and I don’t think she said about helluva boss but she is working towards the end. Season 3 or 4 will be it’s end.

She did say she wants to explore other parts of hell though she just never really said what ideas she has. Maybe they will follow other characters or original ones.

What would you like to see ? I wouldn’t mind one focusing more on the over lords
