c# - multi storied e-commerce with nop commerce -

I'm using nopCommerce 3.50. And it is trying to make a multi-storey. Here are the specific e-commerce registrations for every user such as nopCommerce

The main features I have to pay attention to:

1. Each user (store owner (1 store / user)) Will have its own subdomain.
2. The user will have complete control over their store.
3. They can change the subject or configure any setting as an administrator of NOP Commerce.

So what am I thinking:

1. Create a new project (My project).
2. Resolve a link with it
3. When a user is signed up, they create a new database in the form of a non-commerce.
4. Specifically the name database for the user.
5. Store the DB name and all user information in the mother project.
6. When the user is signed in, obtain the user DB from the db and set the path to the nopCommerce solution db-path.
7. When a user logs in, the user is redirected to the subdomain.
8. and uses the same server-side and client to load related databases for the user-side code.

Is it possible or is there any other better way to do this?
