A framework

So I've been thinking more so than writing these days, doing some research on what direction I would like to take the longer stuff I've been posting. It's all various parts of the same thing, just hard to keep track of as it skips around in time and it probably won't all make sense until it's all on paper. But I'd like to toss out the macro level ideas for a little feedback.

Title: A Eulogy For My Father - This stems a from both how I stopped believing in God, as well as my own father.

Main Character: I'm thinking what I can do here name him Lucifer, but refer to him as Luke and not reveal the full name until the end.

Plot: Basically, invert the roles of God and the Devil in regards to good and evil, but have God played by the sadistic father [Michael, for a play on the archangel Michael], and the Devil played by the altruistic son [Luke/Lucifer], but still try and maintain the other aspects of their traditional religious roles, i.e. that God is not to be disobeyed and absolute etc, and the son is cast out to wander the earth and is the great tempter/betrayer. I guess there will be some challenges to the "lowercase" father/son relationship as well.

There is a lot that I need to get out of my head onto paper, but I'm starting to get the feeling that it will take perhaps a few years to get it out since I have to do this in my spare time. Any biblical references that I should look into would be appreciated. I've found that Lucifer is never actually used as a name for the Devil, merely a misinterpretation of the Latin in an old testament passage, but who can ever pass up on playing games with cultural misinterpretations...
