Would this be a good project?

Sorry, I couldn't find a section dedicated to DIY. While my passion in this hobby is two channel stereo for critical listening, I also have a basic 5.1 surround system that uses Infinity Classia C336 towers. I also have the matching center channel and bookshelf speakers for rear channels. This setup is far from high end but the gloss black speaker cabinets (at least to me) are beautiful, unique and appear to be well made. The towers use three six and a half inch woofers, one 4 in midrange and a 1 inch tweeter. After all that rambling, here is my question. Since I like the cabinets so much would it be worth replacing all the drivers. crossovers and wiring with premium components? If any of you could give me your opinions or steer me to a forum that could help me it would be greatly appreciated. Thanks
