It would be possible...clowns have been known to take up residence in a large assortment of LPS corals(leathers too!)
Mine currently has a gonipora as his favorite place to be....
but I have heard lots of stories about corals suffering from the attentions of a clown fish...so if it does happen I'd keep a close eye on the situation.
