Character motivation. I'd like to know more specifics about the twins and why they're doing what we all think they're doing. This is a key plot point because they're the ones pulling you in from an alternate dimension, presumably multiple times, and I want to know if this is really the easiest way to accomplish what they want to accomplish. I suspect it's not, and that causes some of the plot to fall flat like a series of dominoes.
In the ending, when they pull Booker through the tear to the shore, before taking him to the lighthouse, Rosalind mentions that he is their "hairshirt" (something they have chosen to make their life difficult/unpleasant) like the AD mark is Bookers (for letting them take Anna). This is because they were in part responsible for taking Anna/Elizabeth (Rosalind was the one who opened the tear with her machine and Robert the one who collected Anna from Booker).
When their machine was destroyed and they were scattered across the different multi-verses, they became remoseful for what they did (see the "hairshirt" reference). Therefore, they decided to stop Comstock from existing and enlisted the different Bookers (as can be seen from the Heads/Tails scene early in the game with all the marks in the Heads column) to help achieve that goal.
You also get the impression they have tried other ways to acomplish their goal through the "Things get set in motion."/"How would one know how far back to go?" exchange.
This, but perhaps they also felt they needed to make Elizabeth a god with Booker there so that she would do the "right thing" instead of just smashing the world like Comstock wanted her to. During the story both Elizabeth and Booker learn to care for each other, it's not just Booker.
