It'd be a one time use, for if an admin wants to reset all data but keep altars, or if data is somehow lost and they don't want to reset the world.
Possibly having the command slowly check each existing chunk for what can be identified as an Altar, finding the parent block and creating an altar there., then and give % completion of finding them.
Perhaps changing the design of Altars so that above it will always be a certain air, surrounded by stone brick, and/or below it will always be only 1 block of bedrock surrounded by anything else besides bedrock, might make it easier to detect Altars by looking for these definitive structures.
