The Children theme kits could be combined in a new EP for kids featuring an update on skills and skills training from adults (Adult occults training their youth.) I'm not interested in the children's themes unless the gameplay advances their skills through adult mentoring in a new way.
I like Sunrooms and Porches for build/buy/gardening and hobbies DLC.
I like Boho Surfer Bungalow for Sulani build/buy DLC
Honestly none of these would be new and refreshing gameplay for me if I had to choose and pay. Most of these ideas are all extensions of what the game has already offered within the last 10 yrs.
The Luxury Yurt idea could have been added to Outdoor Retreat right away. I want Van Life even more for it's unique gameplay that it could offer to the game with the hint or hope of vehicles more than Luxury Yurt.
