As for combat effects, to be realistic, the plane has to be released in late 1943. This should give the Japanese a slightly better defense against the Americans at Truk and the Marianas. However, the Americans would use better planes for their carriers. One thing is that, if the Americans lose 100 more planes and the Japanese 100 less, along with a carrier saved, the Japanese would use the planes more effectively and the Battle of Leyte Gulf comes with 3-4 more Japanese carriers and one less American carrier [if the Americans lose any at the Marianas without replacing it, which is unlikely], the last fight and decisive defeat of the Japanese naval aviation would be at Leyte Gulf. If Halsey splits up his forces as historical, the Japanese might be able to inflict serious damage on the escort carriers, several destroyers, escort ships and some transports before being sunk by destroyer or aircraft torpedoes. But the Americans would attempt to place more submarines in position to intercept the Japanese fleets. The possibility of a popularized large surface engagement between the world's largest battleships would also be possible. Afterwards, the Japanese might not contemplate about using Kamikaze planes, at least until early 1945 with better planes, survival rates and aviators. This is the best case of the realistic scenarios for Japan, though.
Its about the quality of the pilots, the experienced navy pilots lost at Philippine Sea was a death blow. The battle was called the great turkey shoot for a reason.
