What's been very successful through history has been that new religions adapt, displace and take over old traditions. Midwinter celebrations to Christmas and so on, or why not jewish holidays given a new story in christianity while continuing to be celebrated at the same time of year or maybe even with the same food (originally). If one is optimistic, this "depth" of traditions surrounding christmas or maybe other holidays give them a bigger meaning, it can encompass all the different traditions at once.
