Google Reviews Snippet VS Aggregate Ratings - google-rich-snippets

Question

I have a few questions about what happens if I add both "aggregate reviews" and "review snippets" schema to a webpage.
Will the aggregate number of "votes" and the aggregate vote rating be displaced by the number and average rating of the review snippets?
Is it possible for both to appear at the same time on SERP, with the aggregate votes & average score (1-5) appearing above the review snippets?
