I really can't see that being helpful at all. They would want his full history and full psychiatric notes before they would vaguely consider interventions such as VNS. You cant just change your name and effectively reinvent a medical history as you see fit, his medical notes would have to get changed over to his new name.
Your best bet as mentioned before is to go through the appeals process to your PCT. It's often tempting to consider a new option such as VNS as a panacea, but the evidence of it for depression is not currently all that great as far as I'm aware, and as such you may find it extremely difficult to get it recommended on the NHS for you.
