Not sure why you think Moffat recycles -- look at the brilliant originality displayed in the Doctor/Amy story arc in series 5, for example:
-- The Doctor visits with a young girl at various points in her life. She thinks of him as her imaginary playmate while a child, but as she ages she realizes he is something more and is in fact from another world. In the end, he saves her from a great evil and she, in turn, saves him
Oh, wait, or was that "The Girl in the Fireplace"?
Moffat does like recycling his ideas, indeed...
