From the moment I've got my initial plan for Mining & Smithing is: First, I will work with the community and devs to develop a new set of rules and requirements that will govern the kind of work that rework is allowed to perform. We will need to reach an agreement as many of these may conflict. It could require a lot of study and explanations to comprehend the workings of the economy and the long-term implications of any change or absence of them. This consensus is important so that the EOC 2.0 and rWildy 3.0 do not come into existence.
The second step is to reuse the existing designs where they fit into the new framework of requirements. Thirdly, you could design new features and/or take suggestions to bridge any gaps or differences between the design of the framework for requirements and the design.
If feasible, I'd prefer breaking down the concept into smaller pieces so we can all agree and disapprove of parts of it, without having to be acquiescent to the whole thing. Maybe we can agree that the new mechanics of mining are robust and work independently from any debates regarding drop tables.
I've attached an informal listing of the things I believe to be the big questions that need answering. Although I do have personal answers to these questions, most of them are subjective. Therefore, I need to seek out community consensus. You are welcome to share your opinion and argue why others should agree with you. I'm sure there are more, so I'll continue to
