Ok, I have been playing with the layout a little, and I think I have something interesting. I've added a sixth stepper driver (color printing!) and an extra FET (will need another thermistor). Board size is extended slightly, most connectors are nearer the edge. I need to reposition all the aux headers (does anyone really use servos with RAMPS?)
ETA: also added third power input, and moved microstep jumpers out from under stepper drivers.

Btw, the white outline is 10cm x 10cm, which is limit for cheap boards. I know, another arbitrary constraint :)
Couple of things to mention : this new board should be compatible with both Arduino Mega R3 and Due, although I don't expect people to rush and buy this board, it should run with Mega and later ppl can upgrade to Due.
If people want to do the reverse, i.e re-use RAMPS 1.4 boards with Due, then the RAMPS-RIB interface board (or similar) will be able to do that as near as possible. Therefore I think it is worth expanding the envelope a bit with RAMPDS-FD, even if it is less of a straight replacement for RAMPS 1.4.
