The only feature I could have an issue with as a Mechanical engineer is the speed holes in the aftermarket sprocket. They greatly reduce the strength of the sprocket compared to stock by relying on a smaller section area to carry the load compared to the original resulting in much higher stress concentrations. Some of that material is not heavily stressed and safe to remove, but those slots are fairly large. Without running the numbers I do not know if it is an issue for this application though.
If you want to see some interesting sprocket design... Wisconsin Racing posted a video showing the load paths of a sprocket under acceleration (engine braking would act in the opposite direction meaning you can't make your sprocket look like this and expect it to work in the real world).

I have not seen a sprocket fail as you describe on a bike - the chain will break first or rip the teeth off first. I don't think they can generate enough traction.
