Custom Content difficulty - Helms?

[SantagarBrax]

I'm just curious how difficult it would be to add in a graphic for a White Dragon Helm? I'm sure that's a simple custom content option we could all get behind, providing graphics for helms currently without.

An idea: a Custom Helm from Velious but all white, maybe even some red or black dragon wings on the sides?

Anyone else have any ideas for helms without a graphic and what they should be?
