When I get super busy at work I take a break from any work on my games and feel safe that they will be there when things die down.
I second the vote on maybe getting your board repaired it sounds like time is precious and your route of redoing your game would take even more time.
I would just chill on the games that take a lot of work for now, fix the easy stuff when time permits, and hit up Chicago Street Pinball on the weekends in downtown Joliet when you have time off.
