I've made a program in java that let's me resize any craft to any size. It won't be intuitive to know how to use it so I'm going to accept requests to do it myself. Share the link to the craft and the scale you want.
It only uses tinker size. If you want to take a look at the code just ask and I'll send it to you, it's a simple one (no more than 100 lines with libraries, try catches and all included)
@Shigure I've seen you already got it, i'll edit it to add the link in the post
