Two user model problem

My project need an admin for staff and a normal website for normal user. Staff can only login to staffsite and normal user can only login to website. Staff will login to admin to do some management. They can view normal user list and detail and create or delete normal user admin. The two type of user is very different, so I want to write a model for each of them, instead of using is_staff flag. But in a project, I can only have a USER_AUTH_MODEL. Is there a good way to implement these requirements?

Since a project can only have a USER_AUTH_MODEL, I separate the two type of user in two project (staffsite and website).
My currently design and implementation is as follow:

I wrote a standalone django app called member, and implement Member model

class Member(AbstractBaseUser):
    #member related fields

then I create two project "staffsite" and "website". "staffsite" is for internal use, "website" is open for normal user. "staffsite" just use the django built in auth.User. Member model in "staffsite" is just a normal model. "website" use Member model as USER_AUTH_MODEL.
I have two database, one for "staffsite" and one for "website". Since "staffsite" need to access Member's data, so I implement a db router for "staffsite". Whenever I need to access Member's data in
"staffsite", router will route me to the correct db (You can say that I use db to link "staffsite" and "website" together.)
  member app need to install in both "staffsite" and "website", so I will have two copy of member app. This is not good for maintenance. Whenever I change the code in member app, I need to copy and paste to another one. I extract member app and create a standalone app, and after that I can use pip install -e  to install member app for both project and I only have to keep one copy of code.

This design is work, but I want to know whether there is a better way to meet the requirements.
