Actually, despite being the northernmost PNW civ, the coastal environments where the Tlingit lived were still relatively temperate. It's worth noting that PNW men, yes, even as far north as Alaska, went completely naked for much of the year, adding birch bark kilts and cloaks in the winter (or fur cloaks, usually bear, deer, or otter, in particularly inclement weather); even in the winter, they went barefoot. So yeah, Tundra bonuses for the Tlingit would be even stranger than the Tundra bonuses for Russia. The only Native American civ I could see giving Tundra bonuses to would be an inland Athabaskan tribe like the Chipewyan or Gwichʼin, whom I'd consider the darkest of dark horses, or the Cree--but that ship's sailed.
Who said the Huns were viable? To my knowledge, no one was very impressed with that badly cobbled together civ. One might also point out that the Huns weren't European, which doesn't exactly do wonders for your argument.
Being from the PNW, I was aware that western natives didn’t need to wear clothes for most of the year, but I’m surprised that applied even to the Tlingit.
Nomadic civs are fine: Hun implementation was immensely poor but at least a united Hunnic Empire actually existed. The Inuits are nomadic, yes, but they never had settlements large enough to even be considered a city, let alone 25. This also may be a byproduct of their lack of written history, but we are aware of exactly 0 historically relevant leaders who spoke for more than one Inuit settlement, let alone the ethnicity in whole, hence why even though I’m not a fan of Civ 5 huns, they make more sense than the Inuits as a civ.
