I'm pretty bored at watching the same armor sets in my inventory so, why not add more armor sets in SK.
I mean look at Terraria, They've got like 2 dozen armors with each individually have their own perks and stuff.
I'd like to hear your suggestion on this.

Also, I would like to mention what happened when they decided to add more gunner armor.
