What if we had an expansion pack based on moving?

Ever built a house and your Sims don't acknowledge the fact that they're living somewhere else? Their ungratefulness always bothered me; I spent 15 hours building you a giant castle only for you to complain about the decoration. 

So basically, I was thinking that we should have an expansion pack that surrounds the process of moving into a new home. Here are my thoughts:

• A "Home Sweet Home" Aspiration: You complete tasks to make a sim feel comfortable in the home they're living in. You could host parties at your house, have multiple generations there, etc.
• Drifter trait: The sim never settles and constantly wants to move to different places or wants a different house
• Moving Specialist Career: They'd help others move to different homes
• Moodlets:
  • Homesick
  • Fresh Start
  • Overwhelmed
  • Missing Friends/Families in their old neighborhoods
• Build/Buy Objects:
  • Moving Boxes. Those can act as an inventory to place random stuff in, and your pets or children can play in them
  • Objects to put inside the boxes. It can be a stack of clothes that the player chose from CAS and put into build/buy.
  • Air mattresses and temporary furniture
  • Furniture that needs assembling, like the rockets
  • Regular objects used to build your home
• CAS objects:
  • I can't really think of any. LMK if you have any suggestions
• Interact:
  • We know of the boxes; we can unpack the objects
  • Admire the house by clicking the door
  • Basement/attic hunting. What you find is by chance; you could be terrified from seeing a ghost or find some rare collectibles
  • Open garage sales
  • House Party Gift Exchange where they can give you gifts to put into your home
• Empty Home lots where the homes aren't completely empty because they have the usual stuff a home contains when you move but the user can have Moving Specialists put in couches, beds, etc.
