This is exactly the point the Clinton campaign has been making, that caucuses don't matter.  Frankly, with what happened in Texas, we have at least one piece of empirical proof that this is so.  Clinton wins the popular vote by 100,000 and loses the caucuses badly.  The caucuses aren't representative of the Democratic electorate at all.  So many of Obama's "victories" in states are really meaningless.  They're not representative.  So, even if you interpreted the caucus results up to turnout at a primary, that won't work because, the only evidence we have from a single state is that caucuses overrepresent Obama's strength among the Democratic electorate.
