You would need a new topic property in PublishQos, something like:

   <topic readonly='false' destroyDelay='60000' createDomEntry='true'>
      <expiration lifeTime='129595811' ignoreMsgSettings='true'/>
   </topic>

Sorry, no, this is currently not existing.

I would recommend to write a little PublishPlugin, see

  http://www.xmlblaster.org/xmlBlaster/doc/requirements/mime.plugin.publishfilter.html
  http://www.xmlblaster.org/xmlBlaster/doc/requirements/mime.plugin.publishfilter.howto.html

You intercept the interesting messages and overwrite the
expiry timeout to your desired minimum value,
