Some extensions are very usefull, i.e. the Dataflash to store programs or the memory extension, the Printer connector, the serial interface.
Maybe it is possible to design a pcb with most/all options onboard and the user can decide (via jumperfield?) which option he will finally use / or which parts he will populate.
I think the costs of the pcb is not the critical part... our friends in asia offer a lot of cheap possibilities.

Only a suggestion ...
That is what I have thought initially. In fact, there are lots of unused pads already on the PCB just for this. For example, there is no composite video connector, but there is a pad on the PCB where you can solder a cable and an RCA connector to get, grayscale composite video out of it.
Want to hear a funny story?
When I sent the PCBs for fabrication these companies did 10x10 panels, so I thought if I squeeze two CB2 micros in this 10x10 panel, I could half the cost, which would make the KIT cheaper for people too. You can't imagine how many of these decisions one has to take if he has to cut down the cost without cut down features!
There are well thought KITS of course and also not well thought
