The distinction between different registers of a religion is a familiar topic—but I wasn't thinking about it in this thread. I should have been, because it's always a basic question. Are we talking about a popular version of a religion, or about hieratic, heretical, academic, or official versions, or about some entirely hypothetical version, like a rationalized reconstruction projected onto a past in which it never really existed?
If I belatedly remember this whole issue, now, then I think I understand your point better. Christianity spread through the Roman Empire, to the point of becoming the official state religion, but we shouldn't imagine this happening as an ancient Billy Graham crusade in which Romans all came to Jesus. However differently the philosophers and the rulers and the priests on all sides may have thought about the new faith, I bet you're probably right that most people thought of the installation of Jesus as something much like the deification of an emperor or the building of a new temple.
Meet the new boss, same as the old boss, more or less, anyway. Changes of deity happened.
At the risk of overgeneralization, I would say that worshiping one god or another in the ancient Mediterranean was something almost like trying a new brand of painkiller. People were looking for things that worked, gods that were able to give them what they needed/wanted. There usually wasn't a lot of fussing about theological arguments and what is real or not. Gods were powerful beings that one related to in order to get benefits and avoid disasters. When the familiar gods weren't getting results, one did not hesitate to try different ones to see if they worked better.
The people who did take interest in systematizing and explaining divine things were philosophers. Philosophy was always, at least in part, a religious activity, and each major school of philosophy had its view on the nature of the gods. The different schools talked to each other and influenced each other's way of talking about and conceptualizing divine things. Jewish and, later, Christian intellectuals who were trained in philosophy and rhetoric just joined the fray and started talking about divine things in a way that meshed with the Hebrew Bible and their distinctive views.
It was only in Late Antiquity after the political elite of Roman society had largely converted to Constantine's Nicene Christianity that one's individual beliefs about the nature of God came to have society-wide consequences that could be deadly. (Here I am talking about believing in Christianity or not, or believing one Christian theology or another.) Before then, discussions about the nature of the divine were, for the most part, the pastime of a small intellectual elite. This discourse was in no way an integral part of "being religious" for the vast majority of people.
Over the course of the Roman Empire, there were religions foreign to Rome and the Italian peninsula that came to be empire-wide religions, which were more or less rendered in a Hellenized or Romanized way. A couple of prominent examples are the cult of Isis (once a uniquely Egyptian deity that was Hellenized in Ptolemaic Egypt and spread through the Mediterranean via Ptolemaic influence) and Mithraism, which was probably born in East, close to the Parthian Empire, and focused on a god with a Persian name, but had a initiatic ritual along Hellenic lines. Mithraism was most popular among Roman soldiers. If you look at both of these cults in the broad strokes, their genesis and spread is not that different from Christianity's. We are talking about foreign deities who become part of the cosmopolitan religious landscape of the Mediterranean and become Hellenized/Romanized over time, achieving success and acceptance all the way up to the imperial court.
