How to shape an E335 kit build headstock?

So I got most of my kit together and out of sheer vanity, I do want to shape the headstock to resemble a 335.

Want to reclarify that this isn't for personal gain - I always wanted to assemble my own 335 and do not want to sell it - just to be clear.

I'm thinking that there might be a mask of some sort that I can download, print and place over and use a Dremel tool to shape it.
Has anyone done this themselves?
