It's not possible with ANY PDF library, since revisions are specific to the PDF for which they were created.
A PDF revision (or incremental update, to the use the PDF terminology) is a collection of new, modified or (references to) deleted objects from the previous revision. Since object ID's are only unique in a single document - a revision for one document has no meaning on another one. What you COULD DO (though not with iText) would be to "diff"/compare the two PDF files and create a version that shows the visual (or possibly non-visible) difference. Adobe Acrobat on the desktop, for example, can do this.
