Are there any Chinese 28.8K movements that will fit a asian DateJust or Day-Date?

I'm looking for a high beat chinese movement that will fit a asian 21J Datejust, and perhaps later a Day-Date. Will any of the DG models fit into this watch?

I just successfully put in a 4813 into a 2813 beginmariner... so anything that uses a 2813 should be able to take a 4813... you will have to break the dial feet, file down the movement spacer from the 2813, and glue it to the dial, but otherwise it works fine!
