It would be a pretty big inconvenience IMO. Gearbox assembly is already hard enough, as I learned last week.
It doesn't hurt that much to add different mounting holes for the cims. Plus, then you can use a system like what 192 used to tension gearbox belts this year to allow for different pinions to be mounted.

We tried assembling WCP gearboxes. It took us around five hours to assemble two gearboxes due to some unforseen issues. It's a great gearbox design for teams with little manufacturing resources. But some parts, like the sping washers, are really annoying to work with if you have enough machining resources to make it fit properly.
Also, R.C, if you are reading this, there was a slight error in the instuction manual. A 1/32" spacer is explicitly stated to be a 1/16" spacer in the instuctions. Not sure if that's our problem or something wrong with the manual.
