The thing is, the strategy with DP hidan is basically to decimate your enemy lineup turn 1, then finish them up in turn 2. For that bee is important.

However i would switch to FM, that way you can get 20 extra chakra points on his move, thus allowing you to use Hidan AND bee's mystery turn 1 hitting 3 enemy ninjas 2 times.

I would be more on the opinion of switching Danzo from such a lineup in order to increase your firepower turn 2 and maybe add some tags. This is specially the case since Roshi is becoming more and more common in lineups.
