Hibernation Sliver and sacrifices
No, you cannot sacrifice a sliver to Necrotic Sliver's ability and then return it to your hand with Hibernation Sliver's ability.

When you activate Necrotic Sliver's ability, you sacrifice the creature as part of the cost. By the time the ability is on the stack and you have a chance to do anything else, the creature is already off the battlefield, so it cannot activate the other ability.
