This is an interesting question, and one that has many different directions it could go, so I will try to keep a focused response.
If I were to consider the possible parts of western monotheism that could be rebranded for another religion, I would think that they would fall into the traditional parts of the religions that have been shared across time. Those being a set of traditions and rituals that are then tied to a single deity and a prophet, of some form.
Most important of these would be the reissuing of accepted rituals that could be used to explain the new religions methods. Consider, as an example, the trust of a revealed text in the major monotheistic religions of the west. In this sense, a new text could be written/revealed that the new religion uses as a continuation of a previous text in a way to build upon prior beliefs and provide validity to their new beliefs.
