I haven't had to smog any FI vehicles but I have smogged my vette that has several deal breaker items in regards to carb #s. From what ive heard if you bring a list of comparable carb #s as well as use a label printer to label parts in question, there shouldn't be an issue unless it's the most stringent of stations (as long as obd2 is clean of course). I have a good friend with a whippled Harley truck, mid lengths, no cats, and breezed through by bringing in carb #s for similar parts.
