Its a great idea and it may work if you have time on hand as lots of time needed to put structure in place, contact couples (finding bulls would be easier), explain, etc. I would even go as far as renting a safe house and convert it into cuckold club hotel. It should have rooms with video recording capability (if couples and bulls want to record sessions) and couple of rooms to be used for scenarios and converted as needed (charge the hubby) like public display of wife when fucking bulls or garage sex etc. Good luck.
