Yes. I'm convinced they will all sound "passable" in the context for which they were designed. They would all work as practical music to which to waltz, without the music seeming weird to the dancers. That doesn't mean they would all be particularly great pieces of music. I think Mozart will just have been having a bit of fun, demonstrating how easily and formulaically waltzes can be written. The harmony tends to follow a fairly fixed pattern, and within that framework you can modify each bar in several ways without changing its harmony. That helps to ensure that independently varied neighbouring bars will still "fit".
