Cantilevers can be installed on touring road frames but not on "fast" road frames. Big tires depends on how big; a few road frames can take up to 32, or 28, but many cannot accommodate larger than 700x25c tires. Other than that sure, nothing wrong with putting bigger tires, a flat bar and canti brakes on a road bike (and the idea is attractive). The balance will be slightly different however.
