I agree cables could introduce signal quality issues.
Observe the buffering added either side of the MTX FDX ribbon cable because of this.
Doing a new board layout is possible, but as Mark observes, because of component clearance concerns, a larger board would result, and thus costs.
I might also need to use straddle (not right angle) edge connectors, which are also more expensive.
There would still be the problems of accessing the SD Card slot and the buttons on the GODIL.
The other point about the market size is also a fair concern.
I do have some time, but at the moment I'm not sure this is a viable proposition.
