Yet you can have a wildcard in the template definition. Isn't the parent just an extension of the template.
Example from the tiles web site.
the wildcard-based style (available by default):
<definition name="test.definition*.message*" template="/layout{1}.jsp">
<put-attribute name="title" value="This definition has a message:
{2}."/>
<put-attribute name="header" value="/header.jsp"/>
<put-attribute name="body" value="/body.jsp"/>
</definition>
