Prime frames and default skins

[Latiac]

I've been thinking for a while, and have casually created a thread every so often about this - We can put default helmets on ou prime warframes, why not default skins that return the model to what it was in the non primed version? Surerly it wouldn't be that hard to implement? - Same with Immortal skins, While the immortal skin looks really nice on some frames, (Nyx) It doesn't look as good with the gold parts of the prime version. That and some of the textures from the prime version are actually still there.

 

Deluxe skins currently change the model - Which is great, why not a normal skin if you have the original non prime version in your arsenal?
