If you want, and have the ability to get to 150 skill (or 135 skill and a +30% Exceptional Blacksmith talisman), you can make Samurai Empire plate armor, and it will be mage armor automatically when exceptional.
This makes it at least as good as the Barbed kit armor, BUT.....
1. IT requires a higher strength (hope you don't get cursed - REALLY bad if you plan to wear the armor against the last room creatures in Doom)
2. Each charge used is one less potential great weapon you could have made.
So, it's still a coin flip. As Barbed kits are more plentiful and cheaper, I'd just burn them for your armor, like you were already leaning toward.
