You should add a maille aventail like on the native spiked helmet for the Nordic, Nasal, Footmen, Segmented and Guard helmets ( you could even replace the "cap" section from the Helmet and Cap with an aventail too). It woud be a really great addition to the Nordic feel I think and greatly increase the variety. Such a thing would only benefit the project in my opinion. Shouldn't be to hard either.
