Yes, but I think not with the approach you've taken.  Though I am 
unsure based on the lack of detail in your question.

The simple page master can be in your layout master set and never 
used, so it is safest to simply add it without putting it in the conditional.

Is that your document element or a piece of your document?  I'll 
assume it is a piece of your document and I'm guessing you are 
creating a page sequence for each of the <BOLReport> elements:

   <xsl:for-each select="BOLReport">
     <fo:page-sequence master-reference="regular">
        <xsl:if test="ReportType='Term'">
          <!--override the regular master to force an even page-->
          <xsl:attribute name="master-reference">even</xsl:attribute>
          <xsl:attribute name="page-number">auto-even</xsl:attribute>
        </xsl:if>
        ...
     </fo:page-sequence>
   </xsl:for-each>

I hope this helps, though I'm unclear on precisely what you are 
asking for.  Perhaps this will point you in the right direction.
