I think it'd be pretty cool if we could make our own shaders. Say if we visited the Emblem/Shader vendor and paid either lets just say 1000 glimmer for a 2 colour shader or 1500 glimmer for a 3 colour shader. We then pick the colours we want and our character model is alongside the selection screen showing us a preview of how we'd look. Just an idea, don't know if it's been suggested before, thought it'd offer more customization
