The Celtic Gods in the Celtic Buddhism act as Shinto-Buddhist paradigm, I guess that could be the closest to it. Like how Islam acknowledges Jesus as a Prophet but does not accept Christianity or his title as Son of God, Zoroastrianism, being sandwiched between Western and Eastern Buddhism does adopt some parts of it, eventually with modern Zoroastrianism acknowledging Buddha as a Prophet of Ahura Mazda as one of His chosen.
Yeshuanism, is like a loose Bahai equivalent I guess. Derived from Judaism, it's exact relation with Judaism is murky like how Bahai is the same with Islam.
