Do these together do reasonably well earning wounds to rely on as a main source?

In harder difficulties enduring dance is hard to keep up when you re in front lines.

No, even if you stack also warrior stance, superior deflection and so on, unless you actually keep yourself far from the fight (going far from rest of the party) but the best option could be a potion of invisibility or something like it. Without going away from fight, a wizard/monk with self buffs should have better odds than a brawler in earning wounds IMHO.
