I think that was the smartest prediction on this whole webpage. It is one of the only logical explanation to the 2 doors problem. However, i believe that the mythological universe that rick created does not have a logical timeline. For example, when carter meets percy than it must have been before percy went missing, but carter drops hints that they meet after book 3 of the the kane chronicles. This doesnt make sense, because percy would have meet him in the summer of 2009, were carter would have meet him in the summer of 2011. Therefore, the events in the son of sobek must occur after the heroes of olympus series. Because percy would be back at camp. In conclusion, your hypothesis, even though its smart, is impossible.
