Yes, you can combine them. The common people will be duplicated and need to be merged. The TreeShare connections will be broken between the combined database for 2 of the Ancestry Trees if not all of them. So you will want to upload to a new AMT if you intend to continue TreeSharing.
I would advise that you not jump into building the combined database until after RM fixes a bug I've just identified which breaks any possibility of an Ancestry Source downloaded to RM, then drag'n'dropped to a new database, being recognised as an Ancestry Source through the new db's TreeShare connection.
