I used a Rubbermaid "KBD" for a bit with HP_Mini in coffee shops for its PageNav keys before I decided I could live without ther rest bu using the space bar as page down. I guess starting out with crappy keyboards and using Duo KBDs more than any human should have to endure were good training for dealing with the roll up kind.

On the 1400 KBD/Duo hybrid setup I've got your classic good news/bad news situation to report:

1) I was looking at the flex cable setup upside down, it folds over to wind up inside the HDD bay which is more convenient . . .

2) It conflicts with the trackball . . .

3) If you can live with the 2300c's Horrid TrackPad, it will fold under the mechanism . . .

4) If you do so, it then conflicts with the TrackPad's flex cable to get there . . .

5) The caps under the chassis hump in the back preclude modifications to the Duo to implement the function key mod . . .

6) With a function key row-ectomy, it will fit front to back with little or no modification to the Duo's plastics . . .

7) Side to side will need modifications to the side of the Duo's plastics a/o keycaps if not outright removal . . .

. . . but the supports removed are unnecessary and the integrity of the plastics will remain acceptable. So if the 1400's KBD can be disassembled and reassembled (keycaps removed and replaced at minimum) in a workable fashion it's still a contender. I think the best approach is to fab a new flex circuit/cable for the top contacts and etch PCB for the bottom section, no remapping necessary in that case. This is something I've been considering for fixing the flex problem of the stock Duo KBD and to provide a connection path between the Docking Connector contacts the MoDem and HDD bays anyway.

The 1400 KBD graft remains a contender! ;D

And this hack dovetails very nicely with the PB100/2300c hybrid hack as well. }
