I'm not completely clear on what you mean by a preview
document.  It seems you want a complete document except
all chapters but one do not appear?  If that is
the case, you might try using <xsl:apply-imports/> in your
customization instead of <xsl:apply-templates/>.

When you do apply-templates, it is only being applied to
the children of chapter.  But you need the chapter element
template to start the page-sequence.  By using
apply-imports instead, you tell the processor to use
the original chapter template.  Since it is conditional
on the selected id, only that chapter should be output.

If you just want to generate a chapter with its own TOC,
you can do it with a couple of parameters and the
stock fo stylesheet:

rootid="chap_preview"
generate.toc="chapter toc"

The first parameter selects only that element for output.
The second parameter causes the chapter to have a TOC
(which it normally does not have in print).
