I am sure it was mentioned somewhere that in season 5 or 6 BO's will be the main focus and that it may be possible to promote Bo's to captain. At this point they may be able to make it so that you can play as one of your BO's as a captain, would make thinsge asier (can train all 3 different classes and different races at the same time)
Turning a Boff into an alt isn't the same as changing the gender or race of an existing toon. The OP isn't asking for the option to start up a NEW high leveled toon, he's simply asking for the opportunity to change the look of his existing one.
