Looks very credible indeed!
The oddest thing is, that Japan actually nearly got its hands on an actual Messerschmitt Me 262. A complete aircraft was part of the cargo of the U-234, a type XB U-Boot that left Kristiansand, Norway for Japan on April 16th 1945, but never reached its destination due to the German surrender on May 8th.
A couple of years ago I made a model of what such a Japanese 262
might have looked like; I'm currently working on a model of the J8N which did
fly as a companion piece to it.
