Sorry but no there are no data that would confirm your claim.
On the other hand here is another interesting blog that blew my mind since it basically confirms claims that Soryu type has an extremely deep crush depth based on the type of steel used for the hull.
There had been independent claims that the Soryu type operation depth is around 600M with crush depth close to 900M.
I found them doing on some research on the next generation after the Soryu.
Although it is a private blog without any backing within this blog it claim the same operation depth.
It also talks about the power train in which he claims it will be a diesel+lithium ion batteries+fuel cell.
The biggest claim is the fuel cells will generate 700kW to 1,000kW of electricity.
This can be verified with present large scale fuel cell by Mitsubishi Heavy.
The dimension shown within the link is 12.0×3.2×3.2 M. So it will fit in the next generation boat by extending the length to 90m.
