However, changing the past would also mean that countless lives would be affected by it, people would be born who weren't meant to be born and in case that either Merlin or Uther went back in time to change things for the better, both actually wouldn't be able to travel back in time because once they change things, the reasons for them to make a time travel would disappear and they would have never travelled back and therefore never changed things... actually. :-D

It's always a paradoxon to make a time travel and to change things.

Nevertheless, if this is overlooked I'd love to see such a thing. One option would be that, as the time traveller makes more and more changes to the timeline, they remember less and less of the original timeline. Eventually, they would reach a point where they would effectively merge with their other self and carry on, with no memory of any other timeline, so the challenge would be to set the ball rolling for a happy future before they forgot everything. It could be similar to Merlin Sickness.
