Update:
From the looks of it, there seems to be a decent group of people for me to contact a recaster, so I did.
After contacting a recaster I was informed that I'm going to lose my 1/60 head in the process for this recast.
Anyways, the 1/60 head isnt put together like the 1/48 head and there isnt a seam down the middle so the recaster needs to look at it to see if things need to be changed or modded for this recast to work. This might also have an effect on the price of the head. So currently no one knows how much the head is going to cost... including the recaster.
As soon as I find out more, I'll keep you guys posted in this thread.
