...No. That's not how mitigation types work. Having a bit of something else and less of the first thing does not give you the full benefits of both.

How much damage does the percentile mitigation component of Holy Shelltron, Bloodwhetting, or Heart of Corundum absorb? That whole portion, which far exceeds the healing value in any 8-second span that'd require mitigation, does not scale with gear. I.e., the majority of Holy Shelltron, Heart of Corundom, and Bloodwhetting unless holding Primal and 1 or 2 Infuriates, does not scale with gear.

The entirety of TBN, on the other hand, scales with gear.

Again, that's not always a good thing --i.e., if one is undergeared for the given piece of content, in which case content-based scaling would be preferable-- but being a hybrid, under the same (well, less, typically) total throughput, does not give the full benefit of both types.
