Fort Boyard seems like it could be brought back for the UK market but cost is an issue and it could probably only work on a minor channel like before anyway so that makes it more unlikely. It passed most viewers by here and doesn't have the same iconic status as The Crystal Maze which even if people didn't watch it they knew of it. Also, so many elements have been borrowed for other shows since, which if it were to be revived by the BBC or ITV (who are of the few who have the money for it), it would be deemed a rip-off of I'm A Celeb and Crystal Maze by those who don't know the history and that criticism would be difficult to recover from. Where it aired previously was helpful in that it avoided mainstream flak, apart from the "guys only watch it for Melinda" jibes during the Channel 5 era.

Thinking of C5 gameshows from around that time, Greed could be revived but Golden Balls would probably be seen as a better bet. On a side note, Press Your Luck has that contestants being selfish angle without the show being too similar to what we have now and could work. The basic premise of Night Fever and celebs singing has been used since but in knockout formats and also on minor channels which made it seem not worth watching (e.g. Celebrity Karaoke Club on ITV2), but I think on ITV with a bigger budget it would do well.
