the only way ive seen this done is by 6 people having a role class book that being smelter, scientist, miner, cook, mechanic and armourer and you could only chose one i play on a server that has this exact thing but the material needed to craft more class books is really rare in drops and you need 40 so yeah this can be done to an extent as long as all 6 people are active and craft their specific roled items and share it with each other its not impossible just the modes required to do this need to be created
