Simply implement them, put them in the PVP vendor.
You could maybe increase the itemlevel of theese to level 60.
Additional tweaking as you like, but i think they are cool.

Additionaly,
Change the appearance of theese items, for the Rank10 warrior gear looks, so we paladins will have a choice about looks, and PVP gear aswell!

Lastly, it would be nice, to have the bracers, and belts for theese PVP sets to have in the game without class restrictions, they seem fairly balanced for early gearing, and would be amazing for Transmog.
There are leather, and cloth variants aswell, but i'll only list the plate ones here.
