I drew a quick and dirty (but compact) vote sink of Republicans in Brooklyn and Queens. If Bob Turner is to stay it would be prudent for Republicans to push for a district like so.
Basically it rates as McCain won 54% of the vote, Obama just 45%. If I was a PVI expert I would find a way to meld that with the D-R average vote.
It can work if say Nadler is pushed out of Brooklyn, but this gives Grimm a 50-50 district in return. Turner can be quite conservative in this district that rates as Republican as any downstate district could be. Though it is worth noting that Democrats have a high average vote, but as we just saw they were very willing to give their vote to a hawkish Turner.
I do intend to do a statewide map eventually as it is very likely that the current delegation will be the one that sticks around while maps are drawn.
