How might it be possible and it certainly is for a person who is an atheist or an agnostic to live by yet another version of the Divine Command Theory?

Answer:
I think you need to clarify what you mean by "yet another version of the Divine Command Theory".

As I understand the DCT, it is the idea that morality comes from a divine commandment - implying that if god commands something, then it must be good. This leads to some difficulties for philosphers - for example, mass murderer, Peter Sutcliffe, claimed that god had told him to kill prostitutes; yet few people would claim he was doing good.
