I think we can more or less all agree (at least here) that the concept of a "God in heaven" is no longer tenable in light of the scientific discoveries made in the last few hundred years. So while the idea of a God "up there somewhere" is no longer tenable, the idea of a God that is at the heart of existence in the form of the "driving force" of everything really doesn't move God to a more tenable position. Science is working diligently on a ToE and sooner or later we will have to move God to yet another amorphous location to keep the notion of a deity current with the latest scientific discoveries. That I think is hardly any way to treat a concept so important to so many people.
Your conception of God is not functionally different from any other conception of a deity as a creator or first mover of the physical world and everything in it. Whether we surround God with clouds and putti or abstract concepts related to energy, God is still over there somewhere. It seems that what you have done is move him from the attic to the first floor study.
If you find that conception of God satisfying, and many people do, I wouldn't argue that you change it at my behest. I can also see potential pitfalls in such a definition of God. If God can be interpreted as a destination that is apart from ourselves, there will always be someone willing to offer conveyance to enlightenment - for a price. And with that price come all the evils that have little to do with enlightenment and everything to do with control of resources and power.
