I think you should use the name you feel can market yourself the best. Many of those “real name” DJ names we see are often not real, but simply a name one chose that rang nicely and fit in the market. One of the more notable ones is Junior Vasquez (born Donald Gregory Mattern), as I don’t even think he’s Hispanic.
I’ve always felt aliases should be about when you want to play in different sounds, like how Curtis Jones uses “Cajmere” for house music, and “Green Velvet” for techno.
In your world, it’s about the image you want to portray. I would tell you not to call yourself “Dan Von Dun” if you were going to play dubstep or trap, as the name seems more along the lines of trance or EDM.
Think about your sound, and the image you want to portray, then go from there.
