The smart part about that set is that pretty much the only psychic attacks in ou are psyshock and zen headbutt, both of which calculate with physical defence, so on that front this conkeldurr set looks pretty nice, but yeah, you'd only be able to set up once you get rid of m-gard, m-altaria, azu and clef. An alternative to remedy the fairy problem (although on a very minor scale) is to run av, but the difference wouldn't be by too much, and it would sorely miss the soft recovery.
The set does have potential under ideal conditions though
edit, ignore the av part, brain fart
