where game changer intersects with taskmaster?

on a behind the scenes ep, Sam was saying he and the team will really have to work hard to top this past season in terms of coming up with ideas. I think there could be some great inspo available from shows like Taskmaster and Traitors (we've seen Survivor and Love Island-type eps). Or even the great minds of Andy Nyman and the fellows who created Inside No 9. What IP would make a great game changer ep or arc?
