Is it really possible to have a pdf which has multiple pages and each of them have pages which are of different page sizes (e.g. letter, A4, A3) and print types (e.g. Simplex, Duplex)???
you can definately do different page sizes by using different master pages. You can set the paper type for each master page in the object>master page palette.
