You can check out Mel Disselkoen's work, he does something along those
lines.  You can find a lot of the stuff at the website
http://www.mdasplitter.com/.

I haven't tried his methods yet, but a bunch of people have
apparently.have.  I read through the reccomendation a while ago, but I
think he has changed them several times and of course timing depends on
location.  I believe he advocated at one point pulling the queen a week
before the honey flow started for those with an earlyish main flow.  The
queen was placed in a nuc and the hive allowed to raise their own.  The
idea was then that when the flow started all of the nurse bees would be
unemployed since there would be no open brood, which also consume your
honey.  They pack away more honey and if desired the queen can be
recombined back together later if desired.  He also did some work with
splitting to reduce varroa load.  Like I said though no personal
experience, but I'm sure you could get into contact with someone that had
it on his site.
