There are people here with much better scientific data to argue from, but my sense is that this is exactly the wrong strategy: the biggest hump is from "free" to "pay", and most points on the spectrum from 0.01 to "whatever a DVD movie costs" are similarly hard to sell at, all else being equal (market sabotage by people selling apps at 99 cents notwithstanding; don't build apps that will compete at 99 cents).
