Boosting it shouldn't be an issue. I'd rather go turbo though if I were to boost it. Do a nice bottom mount comp turbo setup or wait and see what Radowski can do with his stock dme e46 m3 turbo. Customizing things like piping and stuff isn't really an issue, its more the electronics and there is yet to be a true stock dme tuned turbo s54 out there that I've seen. I'm not a fan of standalone EMS. I think the S54 is only taller since is has a larger deck height than the s52 to accommodate the stroke.
