How about something like:

<xsl:template match="@*|node()">
        <xsl:copy>
                <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
</xsl:template>

<xsl:template match="*[not(*)]">
        <xsl:copy-of select="."/>
        <xsl:copy-of select="$file2//*[not(*)][count(preceding::*) =
count(current()/preceding::*)]"/>
</xsl:template>

You would apply this transform to file1.xml and reference file2.xml
using the document() function.

You could speed it up by using a key for the lookup into $file2 as the
heavy using of the preceding axis would likely make this very slow.

If there are a different numbers of leaf nodes at the same point in
each file then you would need work on the level above, eg:

<xsl:template match="*[*[not(*)]]">
	<xsl:copy>
		<xsl:copy-of select="*"/>
		<xsl:copy-of select="$file2//*[*[not(*)]][count(preceding::*) =
count(current()/preceding::*)]/*"/>
	</xsl:copy>
</xsl:template>

If there is mixed content at the level above (<foo> level) use copy-of
select="node()", but if all your text nodes are contained by leaf
nodes then this should be fine.
