The love, peace, and truth part is interesting. I've viewed it as a rotated Triforce, meaning that Ravio is wisdom, rather than courage, for instance. This would make Hilda power, and Yuga bravery, which all tracks. If we go with love, peace, and truth, it should align with the characters. It makes the most sense, for how the characters act, for Ravio to be peace, Yuga to be love, and Hilda to be truth. (Unless it's Hilda's love for her people, but I'm not quite seeing Yuga's possible connection to truth.)
Over all, I think it's plausible.
