You may want to check out Santeria and Candomble. Also, many practitioners of yoga, including kundalini and siddha, remain in their central Christian religion...until they realize what their Christian religion is all about. Even within the Christian faith, there are "pagan-like" practices (and I'm being politically correct here without naming sects, congregations, etc.). So yes, Christopaganism is out there.
When I was a practicing pagan, the only thing Christian I found important was the Holy Spirit because I once believed that the mystical "Flow" was exactly it. Church was out of the question because of time. Practicing pagan rituals and self knowledge is consuming. Who has the time to "serve two masters"? I celebrated Easter and Christmas as eternity of the soul (Christ consciousness) and reincarnation; besides, the "outer" trimmings of those holidays are pagan based. My family knew my former pagan status, and it was something I was absolutely proud to admit because I got results. In that line of paganism, material results are extremely important; otherwise, one's practice is all in the mind, as in "mental." And I mean GREAT results: psychic gifts are part of that equation. Unless something otherworldly or life-changing happens to a person, leaving that type of paganism (channeling with wizardry) is unthinkable. With all the goodies and all -- I think, not. On the other hand, without the will of "a god," one's pagan practice is ABSOLUTELY fruitless. By the way, I'm selling all of my crystals and minerals and things on my website, for I am traveling lightly nowadays.
I'm sorry but you are wrong about Santeria being Christopagan. The Rules of Lucumi is a pagan faith that only syncretizes for the sake of outsiders getting a general idea of what the different beings are. Even then, the syncretizing is almost always exclusive to just comparing Lucumi saints to Catholic saints.
For example, my guardian angel is Ochosi. The angel of divine justice, hunting, animals, the forest, and witchcraft. His closest catholic counterparts are Saint Norbert & Saint John The Baptist. There are plenty of similarities between the two, but as you read further you begin to understand that they are not the same being and it was just a mild comparison in hopes that people will open their minds about who the Lucumi Saints really are and stop calling them demons. The comparisons started when the African slaves were basically being told you are christian or you are dead. When they were forced in such a manner they even went as far as including a crucifix into their practice(among other things), and some people today still use the crucifix out of ignorance. Once again I will repeat: The Rules of Lucumi(Santeria) and Palo Monte(Paleria) have absolutely nothing to do with christianity, in fact it is the complete opposite... Why would they truly hold any faith to a religion that threatened death upon them?
