Many of the expansions really don't tamper with the basic game mechanics much at all, even with the addition of additional meeple shapes and types. The expansions that really mess with the basic mechanics of the game are 1) The Plague, 2) The Tower, and 3) The Princess and the Dragon (in that order). The Catapult is just off in left field, but all of the other expansions really add to the game and complement each other. Go give them a try!EDIT: I always play Bridges Castles and Bazaars without using the bazaar rules.
