Half of the gear would be a very light plastic and the other half would be a very dense metal.
Is this possible ? The "dentures", dents of the gear would have to fit nicely. Quite difficult actually.

Due to inertia, the lighter material should be on the edge. Two material will be a good idea if you need a sacrificial material to prevent a jam from damaging other parts of the machine.

Yes, the timing gear in some automobile engines are made that way. A metal hub and cogs, connected by plastic or fibreboard.
It is designed to break if there is too much torque, to prevent damage to more expensive parts.

Yea they put a gear like that in the older Pontiac Firebirds but the plactic/fibreglass teeth didn't hold up under the stress. The middle was steel.It was the timing gear.

If you mean the center of the gear in one material, and the outer part in another, yes, it is possible and feasible. You will have to take care of coefficients of expansion of the two materials.
If you mean "cut a gear in two through the diameter", no. You will run in serious problems of resistance to stress.

It is possible.
Generally not a good idea.
What is your special requirement for which you want this?

It is possible, but not a good way.
