In this scenario, I have abandoned most of the melodramatic plot threads that built up both around the real story and various fan interpretations. Vader does not accidentally kill his wife, they are not passionately in love until the end, Vader's refusal to let his wife go as per a murky prophetic dream does not drive him into the Sith (yecch). He simply accrues more and more power, becomes more important on a galactic scale, and forgets about her. I like this because it's much more gradual, and parallels my idea of how the fall should've been.

Sounds like an improvement. The story could definitely have done without those things you took out. Also, a major change could have been made by casting somebody other than Hayden Christensen. I would have picked Heath Ledger.
