Using a few mods and changes to the game saves I have found out how make something very similar to adventure mode. I made 5 chapters each as special as I could possibly make them with Advanced World Generation mod. I haven't figured out with my baby modding skills how to transfer stats across worlds but I shouldn't be that much of a problem. Also dedicated server. Mods I used were the:
Advanced World Generation
Teleportato Mod
Starting Items and Recipes
