The task is to track down how the SwTextFormatColl for the only text node in a new document is created, so it doesn't point to "Default Paragraph Style", but to your new wanted paragraph style.
I guess one can place a breakpoint on the SwTextFormatColl ctor, find the caller that inserts that pool item to the document and adjust. I don't have anything more specific off the top of my head.
