I played about a little with gladiator stance and its mega fun, but warriors arent very flashy compared to us pallys. So how about a similar thing for prot?
Seal of the Crusader (or something along those lines)
x% damage increase, forgoe defensive benefits + loose damage redux from SoTR
AS procs as a x% chance from melee swings, multistikes increase chance by x% per hit. AS would probably need a 'can only interrupt/silence each target once per x seconds' condition adding.
SoTR as main finisher
Bastion of Glory becomes Bastion of Vengance - increases damage of holy wrath by x% per stack
Hammer/Cons for AoE, perhaps DS or a new finisher?
Just something I've been thinking a little about in the pre-exp lull, throw your ideas in for shits and gigs.
