Named packers would be great and most likely indeed not that difficult to implement.
I also like your idea about an option to include different colour dyes in your recipes in order to achieve colours not supplied by the mats you're using.
Could become a thriving little industry to supply those, or could be used as a goldsink if they're npc-only items (not that a goldsink is needed, dappers have so little real value that people don't really care about them as long as they have enough to pay for tp tickets, which is great for keeping things friendly, prevents an atmosphere where players try actively to prevent others from gaining resources in order to stunt their progress, a common occurrance in many mmos).
