Retail owned by multiple households

It's probably unlikely to ever occur, but I think it would be really fun if you could have sims from seperate households running a company together. Here's how I think it could be integrated:

~ You could put under the friendly social an option for the person to join your company once the friendship bar is high enough like with the join household feature but, rather than conjoining the households, you can conjoin the retail that the sims own

~ When you open the shop/restaurant/clinic etc, it could spawn the other person like it does employees (so nonplayable but have interactions)

~ You can manage the comapny from both sims households

I understand that this may be impossible to implent into the game but it's a concept I would really enjoy in the game regardless so I just wanted to see if anyone else would be interested in this idea
