I hope collabs are allowed, then. Anyway, I just read the first half of this topic, and skimmed the second; here’re my takeaways.
@Gilahu, I think it said in the Web of Shadows book or the Birth of the Hagah comic that the masks and armor were made by enslaved Matoran. This always led me to assume that the previous teams told Teridax what mask would be appropriate, and they made the whole armor set at once. Then, Teridax gave the masks back to the teams so they could present them to the Hagah, basically what @TheJerminator said. I could be mistaken, though.
Also, about Gilahu’s points on armor variance: we literally only know that two elements have to be the same between them all, the thigh-plates that the shields. You could make an argument for the feet, too, but we have precedent for differing foot models in a single team. Besides that, we know they must all have a breastplate, pauldrons, and a spear-tip but they can look like anything an artist likes, given the set precedent. Same with elements like the lower arms and legs.
I dig @Hazash 's proposal for voting individually, then electing a team. It’s got potential issues, but if they can be smoothed, it sounds like the ideal solution.
Oh, and a question for @Mesonak : Can the shields be mirrored? If Bomonga holds his shield in the right hand, can the sides be swapped, as long as the design is the same otherwise?
And finally, a general question for you all: I here a lot of debate around consistency, be it 3:3, 2:2:2, etc. How would people feel about a team with completely individual colors? That’s what I’ve always pictured, and am planning to enter.
Also, I hope everyone keeps in mind that, while these are not MOC contests, they also aren’t ‘set’ contests. The goal isn’t to create what Lego might’ve, but what the canon allows, which is much more broad.
