Rename the current Miner & Logger skills to something like Stone Mason & Basic Carpenter while keeping the crafting aspects of the classes.
Then add Miner and Logger under the survivalist specialties as an everyone gets and improves over time. Logging skill will be increased with Tree chopping/stump removal. Mining will be increased with Breaking rocks/ores. Increase the overall amount each skill will take to max out but keeping the perks that Miner & Logger currently have.
This will give more of a global achievement for players to be top logger and miner. Global stats of how many Tree's Chomped and Stumps removed can be tracked along with how many rocks/ore's broken.
