No, EF only knows models which are classes. Defining a collection of interfaces like you do is impossible. However, what you can do is write extension methods to query on which have interface constraints. For example:

IMyInterface { int Id {get; set;}}

public static IQueryable<T> Filter<T>(this IQueryable<T> q, int id) where T: IMyInterface
{
   return q.Where(q.Id == id);
}

Here T is a model which has to implement IMyInterface.
