Your example is still very confusing and I have no idea
what you're trying to achieve. They way to go depends also
what you try to achieve, when you need an exact copy of
the first page the above is the way to go.
Another way is to use a make file (or a ctx-file for ConTeXt)
to add a image of the first page to your document afterwards.
