I actually wouldn't change anything about the standard tracklist of 4. Thematically speaking, it's consistent and tells a story the whole way through (up until "I Was Here," at least).
The way I see it, the album's subject matter is roughly divided between a doomed and successful relationships. Tracks 1-4 deal with the failed relationship, and Tracks 5-10 deal with the fostering, maintenance and solidification of eternal love.
It's only fitting that 1+1 opens the album because it presents the concept of love in a very simplistic and mathematical way, and a successful relationship is anything but simple. This is why the second half of the album, dealing with success in love, takes about three songs of development and road bumps until she finally starts professing a deep attachment to the other person; this section is culminated with End of Time, the affirmation that she has indeed found eternal love.
I Was Here, though not exactly part of the prior narrative, nevertheless fits with the theme since a successful relationship could be taken as "leaving a mark" on this world. The one inconsistency seems to be Run The World, but I can't hate too much on a boppy album closer since I'm quite frankly sick of albums ending on a slow note.
And that is why 4 is her best album.
