I will say, there's enough material in the game, now, to do an Urban Fantasy setting between the core rules and the Voidrunner's Codex.
You've got futuristic vehicles and various weapons in the VRC that you could fluff down a little bit in tech level, plenty of gadgets and gizmos, and then the core rules have all the fantasy you could need. Again, just fluff it up to bring it to the modern era and go from there.
A personal favorite idea I've had about magic could be really good for this concept. The idea that magic isn't "Real" but is real. A Fireball spell doesn't actually create real fire but it does generate concussive force and heat, so rather than being a big red ball of fire it's a neon explosion that is clearly 'unnatural' no matter who casts it. It's not -actually- fire, but it kinda looks like blue and pink neon flames.
