Very often, any attempt to force the outcome of a prophecy only results in getting the outcome you don't want - see Voldemort. Such is the divine sense of humour.
Anything Harry, or any of his adoptive parents, do with the deliberate intent of fulfilling prophecy would then be guaranteed to backfire, helping Voldemort instead, just as everything Voldemort does rebounds in Harry's favour. Meanwhile, the fates sit back with a pizza and enjoy the fun.
This might be one of those times when ignorance is safer.
New ideas from Doug, or other dimensional travellers can jolt wizarding society out of its rut, but that's not a lasting solution - and then there's the possiblity of the muggles undergoing a Vingean sinularity, which would definitely need a different thread to do justice to.
Back on the original topic, I wouldn't leave Harry with the first Doctor - he abandoned his own grandaughter on a post-apocalyptical Earth, for her own good, and the sixth is a little tempermental, but any of the others would be a good choice.
Hand Harry over to the third Doctor, during the Unit years, and he'll grow up familiar with guns and gadgets, giving Voldemort a nasty surprise - Time Lord technology won't be impeded by merely human magic.
