It certainly can be done. The easiest method would be to change the TEAM field for the jersey in question so that it is assigned to a different team. This is done by editing teamgear.dbf using DB Commander. You'll also need to change the JERSEYTYPE to make sure a team isn't assigned two default home/away jerseys. Note that this method can also cause problems with the team you're taking the jersey from, as they will be left without a default home/away jersey.
It's probably better to create a new entry in teamgear.dbf, copying the details of the jersey you want to assign to a new team and use the appropriate ID number in the TEAM field.
The easiest way to create a new entry is to move down to the last entry and press the Down arrow key. A new line will appear, you can then start filling out the fields with the appropriate data (ie the data from the jersey you want to copy, except the ID number in the TEAM column).
