I haven't tried this before (overriding default similarity in a custom SearchComponent), but it looks like it should be possible. In QueryComponent.process() you can get a hold of the SolrIndexSearcher and call setSimilarity(). It also looks like this is set only once by default when the searcher is created, so you may need to set it back to the default similarity when you're done.
