Awkward ghostie

I'm working on a Pony themed board game, and needed an image for the Ghost Pony character.  So, I was wondering if I could use Spirit Shine here, slightly modified (I'd like to remove the horn and just use a Pegasus version of her, which would be easy to do even with my limited artistic skills).  I'd of course give you credit in the game.  I hope to get the game published by funding it through Kickstarter.
