Not exactly the same situation, but I have a pink skunk that is currently hosting my Devil's Hand. The same Devil's Hand is also occupied by a single Sexy shrimp. I have not noticed any problems with the two coexisting.
One big variable though is that I haven't owned a maroon clown, so I'm not sure of their temperament as compared to the Pink Skunk clowns.
Forgot to mention there is also a pair of Black and White Oscellaris hosting a GBT in the same tank and there have been no issues between them and the Sexy shrimp either. Of course, I haven't seen the Shrimp stray from the Devil's Hand and they are on opposite ends of the tank.
