First, I think a complete DLCJ solution for Simpson would be great. It would allow the removal of all the bearings and M8 bolts.
Microswitch homing would be good. I don't use custom firmware yet. Generic firmware will be able to home to the microswitches. (I do the coordinate transformation in software for now. Not that it can't go into firmware. Not all my designs can fit in firmware so I am developing a unified tool-chain that will work for anything I do.)
A well designed DLCJ will not have the string pushing the arms apart. The string drum should be smaller than the contact drum. This keeps the string from getting repetitively crushed. This also allows the string tension to more directly pull the two sides together. See my video below.
Guides are a good idea. I am playing with the idea of a segmented (cut outs for the string to sit in) herringbone gear to prevent axial shift and to provide some rotational alignment during assembly.
I am not sure what you mean by the different wrapping methods that you mentioned. I would suggest 1 repeated figure-8 pattern from top to bottom.

I covered a few pages of paper with math and did some iterative programming to find a proportional drive solution. I always love it when complex math leads to a simple solution. This is such an elegant solution that I am considering it for my beta run. I will have to see.
