Hi @jasonkapadia
Could you please tell me where do you want to do it? The backend or front end?
I’m afraid WordPress doesn’t allow you to mix the query between posts and taxonomies. This page should give you more idea about it: https://codex.wordpress.org/Class_Reference/WP_Query. As a workaround, maybe you can get the posts and taxonomies in variables and order them manually by using PHP code.
I hope this makes sense 🙂
