Yes it can be done, and number 1 is your best bet.

Things to remember:

1. You’re going to want to create new Salt keys in your wp-config.php and bb-config.php files.

2. You won’t have any access to your website until you get all of the domain references in the second database aimed at your second domain.

The way that I did this was actually to get everything fully installed and synced together, and then dropping all of the tables in the DB and importing them from the original, and then tweaking as necessary.
