Disclaimer: This might or might not be a solution as it's just a theory for now. :)

We built a plugin to avoid the "PageName1" type segments when copying a page by hooking into the UrlSegment.CreatedUrlSegment and setting the segment to empty. This will lead EPiServer to recreate the URL segment the next time the page is published, but this time with a more appropriate name.

As it happens, while the page is published with an empty segment, it seem to fall back to... *drumroll* ...the page ID! The segment will however be repopulated every time you save the page again, so you will have to keep clearing the segment or possibly set it to the page ID once that has been established and is available...

Let me know how you get on!

We done exactly this: set the Url Segment using some custom code by hooking into the PagePublishing event. However I also think we've also discovered the issue you mentioned (Page ID== 0). Though our requirements meant that we could work around the problem in a way that may not be suitable for you.

Basically if the page is published first without saving, then the pageId will be zero, which makes sense as at this point the PageData has never been persisted in the database (and so doesn't have a unique Identifier). What we did was to explicitly disallow this scenario (as you'll see in the code below). As I said before , this may or may not work for you.

public static void Instance_PublishingPage(object sender, PageEventArgs e)
        {
            if (e.Page.Property["PageURLSegment"].Value != null && string.Compare(e.Page.Property["PageURLSegment"].Value.ToString(), e.Page.PageLink.ID.ToString()) == 0)
                return;

            PageVersionCollection versions = PageVersion.List(e.Page.PageLink);

            if (versions.Count == 0)
            {
                e.CancelAction = true;
                e.CancelReason = "This pagetype must be saved first before it is published.  This is for url rewrite purposes."; 
                return;
            }

            e.Page.Property["PageURLSegment"].Value = e.Page.PageLink.ID;
        }
