I am in no position to say anything and I'm fine with whatever decision you make, but I think that players should be allowed to replay any of their games for any reason, as long as they both agree on it. Of course, this isn't in the rules and changing the rules after the tournament has already started is slightly questionable, but:
1) It's obviously an improvement with no drawbacks
2) Even if it's not in the rules, people can do it anyway: just don't post the log from the original game, and if anyone is bothered enough to check from drunkensailor, they can claim that the one game whose log was not posted was just a casual game for fun in between the tournament games (maybe that's a little weird, but it's not prohibited, and there can be reasons why people would want to play a game with no pressure in between the "serious" games).
