I have to repeat myself: My issue is not about the imposing from A4 to A3.
I want to produce a file in A4 that *can* be imposed on a folded A4 paper.
So it has to have a page count of a multiple of 4.

I know that the file starts with two pages of front matter and that it 
will have one page of back cover.
In between it has an unknown number of score pages.
Depending on the number of pages in the score I need 0 to 3 empty pages 
between the score and the back cover to "fill it up" to a correct file size.

If I knew the current page number on the start of a given bookpart 
(which I'd start after the score) I could calculate the number of 
pagebreaks that have to be entered.
