Dynamically display previews of files within Document Sets

I have a Document Set Library containing multiple Document Sets. Each Set contains 3 documents, each with a different Content Type.

When I select a Document Set, I would like to display 3 'web parts' showing a preview of each of the documents - 1 web part for each Content Type.

It should work in the same way as the File and Media web part which shows a preview of each selected file in a Document Library web part. Any advice is very appreciated thanks.
