I just published a complete redesign of a previous module I created (an adventure for the Mausritter TTRPG). It looks entirely different and has some additional features that the original didn't have, but the core product isn't new. Would that be acceptable for this jam? Since I'm in New Zealand, it's been 1 January for a whole day already.

So, the idea for this Jam to encourage people to create something new during the month of January. It's ok for people to get started early, but it sounds like you did almost all the work before the jam started and would have been doing that regardless of this jam's existence.
If that's the case, it's not entirely in the spirit of the jam, but I'm not here to police what does it does not belong in the jam.
It looks like it's available to the other jam participants for free (point 3 on the jam list), so that just leaves point 2: "Support and encourage your fellow JAMuary participants (advice and feedback should be constructive and considerate)."
So, I'll leave this up to you. Are you looking for advice and feedback on your project? Are you down to support and encourage the other jam participants?
If the answer to those questions is "yes," then I don't see anything wrong with your project being included in this Jam!
Ah thanks so much! And thank you for the glowing review on the game! It really means a lot that you enjoy it so much.
Could I ask you a favour? If you have a minute, do you think you could post that review as a comment on the game itself? Itch doesn't show review text anywhere useful, so having it visible there would be really helpful. No worries if not though - just thought I'd ask.
