Boon (or someone else from the MK team) already stated back when the game came out that if you missed an object in the village, it'd turn up elsewhere in Earthrealm. We had huge discussions about this at the time and whether or not it was possible to get back into the village, but regardless of its possibility, you don't need to.
Sure, you can say it's not impossible that there are still things left to be found and unlocked in the game, but I think it's a pretty safe bet that all there is to find in the game has been discovered. As improbable as it seems to have found every object in the game, including items that can only be found on certain dates at certain times, and as sure as the team was that we'd still be unlocking things for months afterwards, the fact remains that the MK community still found just about everything within a week of the release.
