I don't think this will work, if I understand you correctly.

According to the excellent book "XSLT Programmer's Reference" by 
Mickael Kay, <xsl:import> is a top-level element, and xsl:choose is 
not. In other words: xsl:import must be a direct child of the 
xsl:stylesheet element, while xsl:choose is an instruction and must 
appear within a template body.

I still believe XML catalogs are the only "clean" way to solve the 
problem.
