As someone who has run a summary schedule for a season the constant tease (even though there is no official summary for this show) is just something that would make me very wary about your always wanting to sign up, but never actually doing what needs to be done to get a slot.
The "joke", that is what it feels like to me, is getting kinda old and IMO it is time to either poop or get off the pot. My frustration with "joke" is what prompted the soapbox.
Some shows are more snarktastic than others and this having kids would effect how one does the summary, but the maybe I will if I might ever feel inspired just doesn't make me feel good about ever getting a summary slot. I would never know if you ever intended to follow through and I would want that slot to someone who actually wants one and cares about doing a good job of it.
I think changing the "town" could work to keep it fresh without having to go too twisty. You could do a "colony" rather than a frontier town or something like that, but there are a limited number of these sorts of things that might work. You get a similar here you are with all your supplies now make it work sort of set up out of that fairly easily. Having a different time period could lend to a different set of challenges that could work as well.
