I like my ergodox pretty much, and got it a new tenting yesterday..

Along with my Kensington Trackball Expert

Yet it has something to be improved, especially the flat thumb cluster.
Thus I have spent the last couple months working on the thumb cluster mod. It is not finished yet, because I only got the right hand side built, but I am so excited, I got to share its current (ugly) working form. And here it is

With my hand on it.
I have pull the thumb cluster closer and higher, thus more keys are readily accessible now.
It might take a few more months and more polishing before completion.
This is a work-in-progress mod. Comments and suggestions are welcome...
===========================================================
Update: Here is how I did the mod
1. Cutting the PCB

2. modify the shape of the thumb cluster PCB

3. Connecting the two pieces using a IDE cable

4. wiring and soldering

5. drilling holes on the PCB and attached a plate to it

6. attach the two pieces together

If anyone is interested, I will post more detailed pictures.
