No. Merit in the world to come is only possible by studying the Laws of Noah and accepting the Oneness of G-d. Noahides are not to form new religions or setup partners with G-d. The Torah is forever and does not change. Those who identify as chr’stian deny the fundamental foundations set in place to help us avoid idolatry.
And further, the only possible connection with G-d is when G-d opens up such a possibility. Therefore the relationship with HaShem only exists in reality when we relate to Him in His Terms, meaning that we accept His Will and we keep His Commandments because He commanded us.
