The simplest approach to enabling preview for any file format is by providing a transformation component (Java-based implementation, or simple configuration, if you have an external command line tool/script that can do it) that is able to convert a epub file to e.g. a PDF. A more complex approach would be to integrate a client-side preview component that can natively handle epub.

Some sample projects and blog posts I consider useful on the topic

Custom Previews in Alfresco Share - Parashift 

GitHub - cetra3/md-preview: Markdown Previews and Editing for Alfresco Share 

GitHub - keensoft/alfresco-zip-previewer: Alfresco ZIP and RAR entries preview for Share 

I hope these can give you some ideas on how to do what you want.

you can convert epub to pdf with "calibre". It has a command line utility  "ebook-convert" which should do the trick.

You then just have to configure a content converter (and an ebook mime type if not already defined)
