Nice try, and it looks like this should work,
but it won't .  8^)

The <xsl:choose> element is an instruction that must always
appear in a template body, so it cannot select which file
to import.  And <xsl:import> is a top-level element that
must always be a child of <xsl:stylesheet>, so it cannot
be inside an <xsl:choose> anyway.

XSLT is a funny programming language that definitely
takes some getting used to.
