Tanning/Curing lingcod skins - keep the blue color after curing?

It's been a few years but I want to cure some lingcod skins and I really would like to retain the blue skin color after curing.  There is scant information online.  Kirk at MFN has a blog post that says it might not be possible.  A search here yielded not much.

Anybody have any ideas?

I did it according to Kirk's instructions. There's a post in the craftsman corner section on here I think.
It completely works, but the skins do not hold their blue color with anywhere close to the same vibrancy as fresh skinned. It might work to cure them and then dye them when they are dry, like taxidermists do.

I wonder if using an initial soak with laundry bluing or blue fire brine would help.
