You should be able to port the armor mod to DS2 without spending 6 months at it. I've just ported 120 armors from DS1 to DS2 in less than a day! 2787 files, 76 folders and 85 Mb in size. http://siegetheday.org/?q=node/1607#comment-42029
The armors were actually copied from the DS2BW Adept versions to save time but no alterations were necessary. The DS2BW Adepts files were identical to the DS1 base versions except for being converted to dds format to limit their size. RAW format will work just as well but be about 60% bigger in size.
You were worried about the time necessary for making alpha channels for DS2. However if the armors worked in DS1 they should work without problem in DS2 without any alterations. As I said before it's a matter of making 21 odd duplicates for each armor texture but file renamer helps a lot here. I estimate that it saved me 95% of the time required otherwise.
To help you out I will convert the DS1 Adepts specific armors from DS2BW Adepts that I didn't include in the pack for the Legendary Mod as they weren't original game files. Some of these you created yourself.
This way you will have a framework already set up for you for converting your files plus something ready if you want to continue creating new armors for DS2. Give me a day or so to set everything up.
Most of the "armor" more like outfits with shorts, tank tops, halter tops. I could port them over but they would show a light human skin on both cat mansion and standard characters since none of them have alpha channels which was normal for ds1. Now what I am planning to do is create an alpha channel for several of the best ones then clone the image with alpha channel a few times to support cat mansion female nine images, male one image, dwarf three images, utraean three images and half giant three images. Then for the standard characters the same number of images repainted for the correct skin colors. Yes it is not an issue for armor that shows no skin but for outfits that do it is a bit more work. even a sleeveless shirt is an issue.
