Blindfolds aren't limited to any armor type, and it could easily be alleviated by having visual blindfold models as a permanent part of the Demon Hunter heads. If you choose to wear a helm on top to cover that, you can. If not, leave helmet off and there you have your blindfolds. Any type of armor or helm is a stat boost, just like gear for any other class.
Aside from all this, even if the Demon Hunter class for whatever reason was unable to wield the Blades of Azzinoth, it wouldn't be a problem at all, for two big reasons. One is that even Death Knights can not wield Frostmourne, and suffer no less without it, so Demon Hunters would not either. Two is that the Twin Blades are not transmoggable. All that needs to happen is to allow them to have access to Transmoggable versions of Warglaives, which could include the Twin Blades model (with new texture).
Sorry, but legacy gear doesn't define a class.
