What exactly are you trying to achieve by using the MoreLikeThis handler? I created a patch that adds MoreLikeThis functionality (available in the Standard request handler) to the Dismax handler in http://issues.apache.org/jira/browse/SOLR-295 <https://issues.apache.org/jira/browse/SOLR-295> which may be of interest (although unfortunately not quite the same as what you requested).
As far as I'm aware, there is no real need for MoreLikeThis to be a standalone request handler in its own right (and to be honest the current implemetation feels a bit clumsy), rather it should be incorporated as a "plugin" or search component in the Standard and Dismax handlers (like the way Facets, Highlighting and Collapsing currently are implemented), which is what Ryan is trying to achieve with SOLR-281. I'm hoping the "search component" idea will gain traction and support soon as I'd really like so see the Dismax request handler support MoreLikeThis functionality soon!
