What if the hull of the Amagi, which was being converted into a carrier, was not written off after the Great Kanto quake?
How might keeping Kaga as a battleship (no longer needed to replace Amagi) have any real differences to how the Pacific War turned out?
The OP meant that Kaga gets built as a battleship and Amagi becomes the second Japanese fleet carrier and IMO the Amagi/Akagi were better carriers than Kaga, at the very least Kaga was 3 knots slower and had worse deck armorJapan defeated sooner. Let's face it their battleships didn't do very much but present themselves as targets. They got way more use out of their carriers.

I knew that, OP didn't but I didThe Kaga was slated to be scrapped under the terms of the WNT - look it up. As Matt points out with the Amagi surviving the earthquake the Kaga wouldn't be completed. There is clearly a problem with the OP if both ships are to exist.

However your comment implied that you thought Kaga would just be built as a battleship, no Amagi as a carrier, rather than Kaga being replaced as a carrier by the slightly better at the job Amagi
