I would second the suggestion to look into the NPPL....
Before it was introduced a friend, at a gliding club, couldn't get a PPL because he had an artificial valve in his heart (he didn't know he had a problem until he went for his PPL medical).
When the NPPL was introduced he investigated and was allowed to fly with the condition that he was either:
- Alone in the aircraft
OR
- Dual control aircraft and the person in the "P2" seat had a current licence
Effectively the only restriction was that he couldn't fly passengers without another pilot in the right seat.
Go for it - you never know.
