I don't promise it'll be thourough, but it'll be better than I did in the thread on modding that inspired this. 
So I accept the challenge. Give me a character concept. I'd tell you how I'd do with a minimum of adding new classes. I'll work only with the core, but I don't promise not to toss in a few 'feat suggestions' or 'prestige class suggestions' that most DM's could probably work into decent feats and PrC's no problem.
Challenge me. If I can't do it without adding a new class, I'll readily admit it.
[NOTE: Swashbuckler-style I concede is a needed D&D class...and by that I mean a Dex-based front-line warrior who focuses on mobility]
