Copying Content Databases from one farm to another recurringly?

I have two farms A and B. In order to refresh farm A from farm B on a recurring basis, I am,

1. Performing Remove-SPContentDatabase from Farm A
2. Restoring the SQL Content Database from Farm B to Farm A
3. Performing a Mount-SPContentDatabase on Farm A

The first time has worked fine. However, my question is - If I repeat the process 2 months from now, will Farm A have issues with the next copy of the SQL content databases? Mainly will the remove-spContentdatabase allow me to mount the new database without a GUID conflict??
