I consulted with a pro luthier, and I asked him about moving the neck instead of the bridge (actually I sent him a capture of your messege) and he thinks it could be done, I guess I'll give him to do this, I had enough of this guitar.
I think you're right, it is a custom order and I asked them to check the scale length before they sent me the kit, I was told that it is "spot on" in these words.
