The BR-S style lips are a good fit on the Non sport/AMG pre-facelift models(96-99). There are a few modifications needed for the facelift years (Non sport/AMG).
One of the best looking front end mods/conversions I've seen, was someone molded a 211 E55 bumper to the front of a 210. Anyways if you mold something custom I'd be interested to see the results.
