Sorry if these points hve been discussed, I have not read the entire thread.
1. You can repackage Kodak kits without permission. (the unofficial word is "go for it!") So repack away. However, the solutions are packed under nitrogen or sulfur dioxide in a dry box to maintain stability. Make sure this is done. The Formulary repacks Kodak kits and they do it under Nitrogen.
2. Trebla uses original Kodak formulas for their kits. It is not repacked AFAIK. They mix their own. They are mostly former Kodak engineers who set up the company. AFAIK, it is not simplified.
