Not really.  It would be sufficient to compute a special "book hash key"
before looking up the board position in the book.  Because it wouldn't
be necessary to update this key during the search, the cost would be
almost zero (the time needed to compute the book hash key would be
just a tiny fraction of the time needed to search for this key in the book
file, anyway).
