All of these connectors are around $2 for the male and another $2 for
the female in 100K quantity. The main use of these connectors is
accessing the LCD controller.

Alternatively you could mount a connector that will directly accept a
LCD cable like this one:
http://search.digikey.com/us/en/products/FH12-50S-0.5SH(55)/HFJ150CT-ND/1110390

Then pick a range of LCDs with identical pinouts and set everything up
to work with them.
You need another similar connector for touch screens but it is much smaller.

Now put everything else onto .1 header pins.

Plan B - get rid of the LCD connector and just tell everyone to use HDMI.

Plan C - switch to SODIMM which is an edge connector. That eliminates
the cost of the male connector since it is fairly cheap to etch the
card fingers onto the PCB. Just make the SODIMM card longer, none of
the female connectors limit the card length.
