While I fancy the idea, unfortunately, Tank Stance will always be considered obsolete, unless the devs radically change the battle system. There simply isn't enough outgoing damage to warrant consistent mitigation; not helped by the fact lethal attacks are 100% predictable. No amount of incentivizing Tank Stance will make it relevant. It's frustrating to hear Yoshida lament how Warriors won't use Defiance or Healer DPS isn't expected. Make content where we care less about damage then and we'll actually focus less on it. Ultimate is a perfect example of this. Putting aside the difficulty, it's actually the sheer frequency of damage that forces Tank Stance in more situations than any other content. There is a risk going into DPS at inopportune moments. Bring that risk over on a smaller scale and people will use Tank Stance. But when Immunity through every major buster and have Vengeance up for other bigger hits. Well, what do I need Defiance for?
