Have an existIng installation of SOA, copy your BGEE save game to he SOA save directory, edit it, then copy back to your bgee save directory. Make sure to drop all magic items first or they will be deleted.
That will allow you to access all of BG:EE's usual resources. You still have to move the saves and then move them back, but it's better than using BG2.
