SS,
from what I understand, if you get a SEP Class Rating on your ATPL and keep flying GA types, then your licence will still be 'current and valid'.
All you'd need then for gainful employment (i.e commercial jets) is a Type Rating which hopefully your next employer will pay for.
Again, just my understanding.......
