Here's some ideas I thought of your Show Town Reboot finale two parter DP994.

1: The story begins with Hugo proposing to Rita to which Tom congratulates them.

2: Since Montana Max and Elmyra are the main antagonists maybe they can team up in some way.

3: Montana Max uses a spell to awake the dead.

4: Here's a good one the zombies can be all the previous deceased antagonists from our previous stories such as Clarissa Corgi Portia Poodle The Tiger General Homelander Evil Steve etc maybe Mouse Ka Boom can make a brief appearance ( also are Evil Steve Hamister Retnuh dead permanently now? )

5: The couples help set up Hugo and Rita's wedding during the epilogue Sophie especially helps designed the wedding cake to which Meowth says you really outdid yourself on the cake Sophie you're amazing before kissing her cheeks making her turn red with pride

6: The ending can also tease that cruise ship story you mentioned a while back where at the end The Quirky Quintet receives an invitation to an around the world cruise for everyone in town.

What do you think?
