Keeping in mind any interesting cross corellaries of the UB account and gospels, there are some interesting UB notes on gospel dates and authors, - maybe see if any other historical records can colloborate those points. There is an zany-er gospel called the Talmud of Jmmanuel, its pretty fun, more cosmic, but the spiritual teaching for the most part is pretty spot on, focusing on spirit truth, divine principles, and a kind of neo-humanist social gospel, based on universal law, conduct and principle.
