I think this can be helped if we "nicen" Anakin up, starting back in AOTC: cut him talking back at Obi-Wan in the elevator and in Padme's apartmant, cut him arguing with Padme in front of the Queen, add the scenes with Padme's family (Anakin at his nicest here, I think), tone down his creepiness around Padme, imply, but don't show the Tusken slaughter and cut the following confession.

Same goes for ROTS: cut down his whiny and brooding moments (what little there is) before the turn, and take out every display of emotion after the turn, such as him crying on Mustafar.

You'd probably enjoy my fanedits of EP2 and EP3 ("Twilight of the Republic" and "The Black Knight Rises", respectively), since I do most of the changes that you talked about here (except that I completely cut out the Tusken Raiders subplot and Shmi is already dead and buried when Anakin arrives on Tatooine).
