Something that you are not taking into account is that it is the armor crafting skills that make the augmentation kits. Yes cybertech and artifice can acquire the "special" kit materials but only the armor and weapon crafting skills can make the augmentation kits. Furthermore, it is Armormech, Synthweaving, and Armstech that can make the augments to go into those slots.
I think the biggest wrench in the works right now is the cartel shop and the fact that every piece of equipment that comes out of there is adaptive and moddable, so cybertech is getting a lot of attention.
I think a good solution would be to allow players to buy schematics off the cartel shop to craft the items available there. This would give players an alternative method of acquisition.
schematics wont happen unless the item is no longer being sold or you have to buy a mat from the cartel to make it. they are not stupid enough to loose monies made from the cartel shop with crafter makeable items.
