Provide 'if' task to handle multiple targets

I want to use the same build.xml to build for either JBoss for Sun's J2EE RI.
Currently, I do the following to achieve the effect I want.

    <target name="pick-j2ee">
        <condition property="use.jboss24">
              <equals arg1="${j2ee.type.env}" arg2="JBOSS24" />
        </condition>
        <condition property="use.sunref">
              <equals arg1="${j2ee.type.env}" arg2="SUNREF" />
        </condition>
    </target>

    <target name="construct-classpath" depends="pick-j2ee,use-jboss24,use-sunref">
    </target>
    <target name="use-jboss24" if="use.jboss24" depends="build-jboss24">
        <available property="classpath_id" value="base.path_jboss24"
file="${jboss.dist}/client/jboss-j2ee.jar" />
        <property name="j2ee.dist" value="${jboss.dist}" />
    </target>

    <target name="use-sunref" if="use.sunref" depends="build-sunref">
        <available property="classpath_id" value="base.path_sunref"
file="${sunref.dist}/lib/j2ee.jar" />
        <property name="j2ee.dist" value="${sunref.dist}" />
    </target>

I would very much like to be able to do the following:
    <target name="construct-classpath">
        <condition>
              <equals arg1="${j2ee.type.env}" arg2="JBOSS24" />
              <available property="classpath_id" value="base.path_jboss24"
file="${jboss.dist}/client/jboss-j2ee.jar" />
              <property name="j2ee.dist" value="${jboss.dist}" />
        </condition>
        <condition property="use.sunref">
              <equals arg1="${j2ee.type.env}" arg2="SUNREF" />
              <available property="classpath_id" value="base.path_sunref"
file="${sunref.dist}/lib/j2ee.jar" />
              <property name="j2ee.dist" value="${sunref.dist}" />
        </condition>
    </target>

In a general sense, I'd like the Condition task to do more than set one
property.  It would be nice if you could perform any task just like target. 
Alternatively, target could be controlled by condition instead of just if and
unless.
