I can't say anything for sure right now because we are only getting starting to organize but we will probably begin with listing all the commodities and asigning lore buypoints and sellpoints. After that we will change one commodity at a time in the market_commodities.ini according to the new distribution.
So best case scenario for the near future is a market_commodities.ini with only one commodity changed. This way we can see what the feedback is and how well we can manage the changes. Again, this is not for sure.
