If you're only bored with the households, why not download some from the Gallery? You could search using a hashtag for backstories, drama, or non-traditional.
If you're bored with everything, maybe try downloading a custom save, and moving your current household/s to that save.
As for gameplay ideas, maybe try an occult file with all the occults. Play it similar to a legacy but a rotation where each occult type is trying to build their bloodlines as well as build their world. It kind of combines The Legacy Challenge and the Build Your World Challenge. I've thought about doing this but I haven't figured out how I want to do it. You could even have rivalries and alliances. It all depends on how in-depth you want to go with it.
I'm currently playing a legacy-style rotation with my founder being an alien. With the help of mods, it has been anything but boring. The third child of the third generation has just aged up to a toddler. I just let the mods and game do what it wants and I roll with it. I don't have any rules other than that.
