Yes, you can try this out. Assumed you have blog 1 with a normal admin, editor, author. Now go to your last site blog 10 for example. So to Users > Add New. There are two parts. Add Existing User or Add New User. In the Add Existing User enter the email address for a user from another blog (not a super admin). Now if you view the usermeta for that user in your database you should see something like:

You will also see another row in usermeta  'wp_XX_user_level'. Since a user can be an admin on one blog but a lowly author on another blog. 

The one caveat I found with this logic is the super admin. The super admin will not show these wp_XX_user_level' or 'wp_XX_capabilities' entries in the usermeta information. You will need to call is_superadmin to check if a user is a super admin. They will automatically have access to all blogs.
