I find it hard when trying to dream up the perfect New PT because I am always torn between what I would want if I had a blank canvas to create whatever I think is best, or what I think can be done to edit the existing PT into better films. Even my drastic edits that I have suggested on here aren't as drastically different as I would want them, but I have found that by attempting to edit the material we already have it made me consider some of the questions which are often raised in a slightly different light.

With regards to the OT secrets, personally I will always be in favour of preserving those.

A lot of thought goes into how Obi Wan and Anakin meet. However, if we meet them whilst they are already friends it means that what we are shown only has to enforce this great friendship, not create it entirely. Personally I think this would be better as it is easier, and still works really well (just think of Han and Chewie, or even Vader and the Emperor before the PT came out). This would also allow Anakin to simply mention his step brother without there having to be a full explanation on screen, thus allowing Owen's words more room to be truthful.

Also if we just have Anakin and Obi Wan meet up with Bail as old friends who already know each other from their time during the Clone Wars then it means its another part of the back story that doesn't have to be forced into the new story.

As I said this isn't necessarily how I would have my ideal NPT but from the point of view of editing the existing ones, it can be explained in the new crawl before episode 1 that Obi Wan has begun training Anakin, and that the two helped Bail in the last Battle of the Clone Wars. This then leaves the actual film much less restricted without pulling a Lucas and just throwing everything we already know out of the window. Just thought this approach might help if anyone is struggling how to incorporate certain things from the OT.
