Do I correctly understand that you are transmitting torque through an e-clip groove? If so, that's going to be a weak spot in your drive train. Putting an e-clip between the load-bearing gears and the future encoder should be OK, and between the gears and the end bearings would not be as good as the outside, but much better than between the gears transmitting torque to/from the shaft.
