Unique armor

Would it be a good idea for infinite, 343 to put some unusual armor on the others? Like the halo reach pilot helmet with its iconic skull.

I would like some variant of the Haunted Helmet to return. If not that then maybe a special FOTUS helmet seeing as 343i has a thing for unicorns.

Maybe a unicorn helmet that looks like a unicorn, like a unicorn shaped face cover (going off of vmasterrecon)

I’m honestly most interested in the armors/coatings, etc. that are going to be hidden behind achievements…possibly even Legacy Awards (aside from those already announced-and yes there are still more to be announced).
