It is difficult to answer questions such as these, as there is no standard version of any of the myths. Stories such as these have been adapted over time, so to give you a definitive answer is impossible. Your theory could very well be correct, but focusing on the unique aspects of Greek mythology is what makes it so interesting.
No I personally do not think there is any reason to make that connection. There is no mention of an omnipotent being in Greek mythology. Some say Zeus is omnipotent but I disagree. His power does have limits.
