Convert Genesis 9 texture for Genesis 8.1?

OakMoon99

Hey guys! I really love some of the latest Genesis 9 character textures, but my whole library is based on Genesis 8, not very sure if I want to switch to G9... So I'm wondering if there's a potential workflow that may allow me to convert those textures for G8 figures? 

I've already managed the process of matching G9 and G8.1 base figures, and I also know some basics about Blender.  

If anyone knows a tutorial (or a combination of a few) out there that can make this happen, I would appreciate it a lot. Many thanks!
