I had never seen or heard this set of ideas before, but I have to say that I have dealt here and there with people who say that they don't like Paul, either because of a few items about women or because he develops a theology of the cross and the atonement that is only implied and not fully opened up in the Gospels. These are people who would like to be ethical followers of Jesus ("Love thy neighbor, etc."), but without what they consider the baggage of sin and salvation, etc.
Don't get after me ... I do handle that set of arguments!
Personally I love to preach from Paul, even though (or is it because!?) it irritates some of our folks.
If you want, however, to differentiate Paul from Jesus, ponder how Paul seems to have very little knowledge of the historical Jesus, making very few references to events in the life of Jesus and quoting Jesus very seldom.
