Im not really well up on creating stealth accounts. But i sort of have the same thing. I had an old paypal which i paid off the debt and hasn't been used in over a year. Same with an old eBay account i forgot the password to.
But the way i see it after reading through stealth it's probably better to just kill the paypal and forget about your email as Aspkin said, everything NEW.
Afterall, if you never use it, it wont be missed and there will be less risk of a link or suspension. Emails are easy to set up anyway!
Hope it helps a bit (As i said, not an expert!  )
