I have been toying with the idea of this project for a little while. What if we take the Old Testament tales of Israelite conquest of the lands of the Canaanite nations and substitute "Muslims". This would allow Christians to look at the passages with fresh eyes. We might also want to replace the names of the Canaanite nations with modern non-Christian nations such as Thailand, Cambodia, Laos, etc. Just by changing the names, that whole section of the Bible becomes instantly untenable to most Christians.
It might be interesting to do something like this with many parts of the Bible. Keep the content but shift the context enough to allow the truth of what is actually written there to pop.
