Mount the chip off center to give yourself more room.  Of course this
makes the entire adapter wider by a little bit but unless there were some
extremely tight tolerences around the chip, I dont think it'd be a big
deal.

I found one data sheet that states the pinout of the N and NF chips are the
same, so perhaps mounting the NF so that it straddled one row of the N pins,
then you should be able to just use a single sided board.
( perhaps this is wrong, but finding NF data seems to be hard-ish )
