Greetings to you, HMTM. People are free to do as they see fit, including going to Jehovah's Witnesses even when they know it's not the absolute truth that it says it is. And I am certainly not one to advocate other churches, but non-trinitarians, according to Wiki include: Modern nontrinitarian Christian groups or denominations include Christadelphians, Christian Scientists, The Church of Jesus Christ of Latter-day Saints, Dawn Bible Students, Friends General Conference, Iglesia ni Cristo, Jehovah's Witnesses, Living Church of God, Oneness Pentecostals, Members Church of God International, Unitarian Universalist Christians, The Way International, The Church of God International and the United Church of God.
I think you might serve yourself to read the Steve Hassan books that Flipper mentioned. Also, consider what kind of reception you would get from Jehovah's Witness members in the congregation if they heard some of your radical thinking (radical to them) against the teachings or the Governing Body. While I cannot recommend other churches, there are some on that list that allow you to think/speak/feel as you like. Also, Buddhism and Taoism allow you to do the same.
If you want "Jesus," you can't really follow Buddha, but you could go to the way Buddhism was meant to be and still is when advocates follow their own private path of enlightenment. They really were not supposed to follow anyone, but to become their own Buddha. In other words, you can meditate and apply any part of your Jesus belief to your life without some organized religion to visit on weekends.
I can't quite claim the title of "Non-Christian, Non-Buddhist, Atheist Zen" but that's pretty close.
Here's some commonalities between Jesus and Buddha:
