Not much I can add to what Ed has already said. Apart from the flux density. I ALWAYS try and run it lower rather than higher. Its probably a bit over the top, but you dont know what iron you are using. Dont forget, although you have increased the stack height, you havent increased the window size so I would definately be running your calculations at least a couple of times to see that it will fit. My own transformers, even when using 5%SiGO laminations is ONE Tesla, or in my language, 64500 lines per square inch.

All the best with your rewind!!
