I'm a little confused here Jeff, the authors of the Wiki article on Pearl Harbour talk of the planned third wave of attacks that were abandoned. The Japanese suffered little casualties in the first wave, but damage to the attacking aircraft in the second wave had increased to a point where it was taken into account on whether they should go ahead with another attack.
I'm not sure on whether it's just idle speculation but It had been suggested that the abandoned attack could have caught the carriers returning to Pearl.
On December 7th, when Pearl Harbor was attacked, USS Enterprise, CV-6, was about 200 miles west of Pearl Harbor. Her first notice that war had begun came from one of her own pilots, Ensign Manuel Gonzales, of Scouting Six, flying in to Ford Island Naval Air Station that Sunday morning. He was heard on the radio saying,
"Please don't shoot! Don't shoot! This is an American plane."
Moments later, he was again heard ordering his aircrewman Leonard J. Kozelek to bail out. Neither man was ever heard from again.
As the second wave was departing, Enterprise was ordered to seek out and attack the Japanese fleet.
But, faulty intelligence and bad guesses about where the Japanese had launched from led her to search the waters southwest of Hawaii, where she found only more American ships.
At dusk the following day, December 8th, 1941, Enterprise and her Task Force, low on fuel, came into Pearl Harbor. Working in the dark, in shadows cast by the still-burning Arizona, Enterprise refueled and reprovisioned. By 0600 December 9, 1941, she was underway, clearing the harbor channel and sailing back into the Pacific
So, given the history of her movements, it is very doubtful the Japanese would have found her. She had turned away to the southwest looking in the wrong place for the Japanese carriers and any Japanese planes going to Pearl Harbor as a 3rd wave would have missed her. She did not come into Pearl Harbor herself until dusk of the following day.
