The galleries and shops are still changing, so this is pointless. XD
I'm not sure what what Keith or the staff have in mind for future updates, but I wanted to put an idea on the table just in case.
First, I would like for non-GA users to be able to choose which shops/galleries they want to be able to add to if they lose their GA.
The second thing I'm thinking of is a way to give the non-GA users access to all of their shops or add 3 shops if they're never able to get a GA. What if there was a system to buy shops/galleries with sp like the pet slots in the Millionaire Center? It would make getting the extra shops/galleries hard but not impossible. At least then everyone would be able to have 6 shops. GA users can also buy the 3 shops/galleries just in case their GA expires and they can't renew it.
