Hello Mark - why? Although this is possible to do so, for what reason because it makes no sense. Gone records are not reindexed, they are ignored, or with the correct flags even removed from the index.
In any case, in Nutch 1.x the CrawlDB is read (optionally in trunk i believe) and the number of 404's in the segment are passed as well. With some clever key/value passing In indexermapreduce, it is straightforward to get that value beforehand.
