It should be possible for an XSLT implementation to use asynchronous retrieval of document() using variables.

Say, if you had something like this

<xsl:transform ....>

	<xsl:variable name="doc1" select="document('doc1.xml',.)"/>
	<xsl:variable name="doc2" select="document('doc2.xml',.)"/>
	<xsl:variable name="doc3" select="document('doc3.xml',.)"/>

	
	<xsl:template match="/">
		<xsl:apply-templates/>
	</xsl:template>

	...
</xsl:transform>

The declaration of the variable could start the download/parsing process but
not block further execution.  Only when the variable was used in an expression
would the template evaluation thread need to block.

I do not know if any of the existing processors implement this type of behavior,
however it would not seem to require any changes to XSLT to approach the
performance that you estimated for XInclude.
