Character Skins

Will there ever be a MTX where we are able to change our character skins? Like.. If I were to play a witch class, then there should be a MTX that changes the appearance to marauder for example. But what bothers me is the size of the base character models and how they stand in particular. Like I don't like how the templar has his right hand on stomach or how scion has her head slightly tilted which is why I prefer marauder, duelist or shadow base model. What do you guys think? Does anyone else feel the same?

This would be a MTX that I'd purchase, even if it was only visible to me. (no change in display to others in town/party) I'd consider it reasonable to cost up to 400 points per class. I like playing totems, but dislike the Templar (model, voice lines, etc)

Doubt it will ever happen, but it's one of the few MTX options I'd pay for.
