Mlp Sprite Collection (Still Working On)

There's a certain version of Spitfire one of my friends wants to see in an RPG I'm working on. (I believe, from how he described it, it was the one where her mane looked a LITTLE like Rainbow Dash's with Spitfire's fire-like pallette while she was in her Wonderbolts attire with only the face cover off) Can you research the design and possibly add it? All I know is that it was before Wonderbolts Academy's design. I already gave pre-credits to any spriters I use sprites from, but I'm wanting to be specific about it to have a clear idea when I finish the Demos for two of the stories, because the game's a multi-crossover between multiple series.
