@Crosseye_Jack has been talking about this with some of the mod team. Revlo will be providing a lot of access to their system so we can save the salt that has been earned. It will be something he is working on so we can have our own system in the future.
We'll try to keep everyone updated as the last days of Revlo come closer and we have a solution. But the goal will be to not have all our mining be in vain! Fear not
