Turanil, I'm going to make it compatible with both the PHB and d20 Modern, so everyone can use it. I wanted to use the defense system employed by the d20 modern srd, so that was my initial choice, but that system is not hard to adapt with the SRD being available to anyone that knows roughly how to make a character.
Soon, d20 future will be available, and Grim Tales should get a good success, and I very like d20 modern but there isn't any setting (or is there?) except for Urban Arcana that I find dubious. On the other hand, there is so many D&D settings around...
So my suggestion is to make it clearly based on d20 Modern / d20 Future. For mages, just include new FX mages / witches classes if need be. If people want to use it with DnD, there is already so many d20 supplements that they could use, but much less when it comes to d20 modern. In fact, d20 modern advanced classes cannot really be made like D&D prestige classes. I once tried it with a class that I first made for D&D, then converted to d20 modern; I had to heavily change the class features (if you want to see, post #10 on this thread ). So, I still suggest doing it with primarily d20 modern in mind.
Just my 2 cents wish of course...
