I think there are some potential problems. From a practical standpoint, such a design may invite players to play toward other people on the course, clearly a liability issue.
Philisophically, I wonder if this would be an artifice substituted for cleverness. A feature, natural or not, that is used to attract the eye of the unwary, to cause him to presume a line of play which is not optimum, might be clever. But to "dupe" the player into playing to a different hole through the device of an artificial "target" seems of dubuious architectural merit.
A policeman can dress up as a hooker and arrest someone who proposes to pay for a hooker's services, but cannot solicit the proposal.
