Assuming gravitons exist, they would be their own antiparticles. What would happen if two were to collide and annihilate?

Single gravitons with wavelengths large compared to the (tiny) Planck scale would be extremely weak wiggles in spacetime. That means they would be very close to following linear propagation equations. Linear equations obey superposition. So they would just pass through each other unchanged.
