Probably not at a restaurant, and if it was, it would likely be stupid expensive. Making it to order in a rush would be a total fuckstorm. Prepping them would take forever and would be difficult to get right in terms of portioning to avoid waste, in addition to tying up a huge amount of bacon for a single item with unreliable sales frequency.

From a staff perspective, no one would want to do it. From an owner's perspective, the increase in labour + material costs are prohibitive. Most likely, the only place you're going to see this is in a mad chef's home experiments.
