That's gonna be a pain in the ass to figure out.The game is weird, and being an alternate universe Big Daddy can also cause some possible confusion. Though the drill launch thing was explained as something too unstable, as whatever they used to power it didn't mix well with the Big Daddies and weren't going to be used anymore. Maybe it was stronger or something, I don't know.
But regardless there isn't really anything to scale Booker to from Rapture even if that was the case. So without their own feats, 10-A or Unknown is the best I can think of.
