Since PC Bang edition G102s sell for ridiculously cheap on eBay, I bought one to try but didn't like the shape. By happy coincidence the sensor and mousewheel location is a perfect match for both the Zowie AM and WMO, which are my two favourite shapes. I originally did this mod on the AM, but Amazon later had G203s on sale for $25CAD which is too cheap to turn down.
In my opinion the G102/203 easily has the best price to performance ratio of any mouse ever as it has a perfect sensor and Logitech's extremely low debounce, and costs less than offbrand/budget gaming mice. It's really a no brainer for a modding platform. Since the G Pro has an identical PCB layout, it will also fit.
The WMO I had added side buttons to from a previous mod so I was also able to take advantage of the G203 PCB having traces for side buttons.
I order to get the PCBs to fit, I did have to route away all the existing protrusions on the bottom shell and glue the PCB in. I used epoxy but I later found out that regular hot glue also sticks to mouse plastic extremely well, and is much less permanent. I didn't want to destroy any of the G102/203 shells, so I had to make my own mousewheel retainers which I did out of guitar picks. Old credit cards probably work well too.
The G102/203 have larger mouse wheels than the shells can take. On the AM I dealt with this by removing the rubber, and on the WMO I just routed the shell since that mouse is ugly anyway.
I also had to relocate the main button switches in order for them to line up with the part from the top shell that presses them. Gluing a flat piece of plastic to the prodders can also help extend the range at which they can reach the switches, or increase the footprint if you weren't perfect in your alignment when gluing down the PCB.
For some reason the AM happened to lose a bunch of weight in the process which I am happy about. Both mice ended up weighing less than 80g.
UPDATE: Made a Paracable for the AM.
UPDATE 2: Added pic of range extender for left and right button plungers.
UPDATE 3: Sanded down the dremel accident that was on RMB.
