There are a couple of problems with these assuptions, I think:
1) Total damage reduction (DR) from difference sources is generally a product, not a sum. 50% DR from one source and 50% DR from another source is 75% DR, not 100%.
2) Boon of Bul-Kathos is applied before cooldown reduction. This means that Boon of Bul-Kathos reduces the cooldown of Wrath of the Berserker to 90 seconds and then CDR is applied. You would need ~78% cooldown reduction to have continuous Wrath of the Berserker. I don't think that this number is possible to achieve for barbarians.

That would mean to sacrifice all 3 of the end game sets and basicaly gor for Borns chest and sword (get 10% cdr on sword), captains crimsons set, 10% cdr in parapoints, cdr on shoulders and on another weapon. ud come around 60% not sure if you can make somthing strong with that
If so can this math out properly?
Pride of Cassius belt + Boon of BK passive + Wrath of the Berserker//Striding Giant + Ignore Pain skill + ~60-70% cdr
= Damage Immune + 100% uptime on Wrath and 50% dmg reduction to party from Ignore Pain rune
