Updated my mods to 1.11 (only minor changes, see the change log for details) Enjoy: Biome Height Tweaker: easily configure custom heights and variation of the biomes. Can be used to selectively amplify your world, or just make parts of it slightly more mountainous/flat. Will work with modded biomes in Default world gen, not compatible with mods such as Biomes o Plenty after 1.7.10. Default World Generator (Port): my port of fireball1725 original Default World Generator mod to versions of mc 1.8.9 and above. Allows a pack creator to set or force the default world type, and any customization screen. Easiest to configure in the Mods -> configuration gui as this will use the same gui for customization screen as the customize button on the new game screen. ezWastelands: Need a highly customization wasteland terrain with no resources to be found for your modpack, possibly something loosely based off of regrowth or crash landing? This is it, recommended to be used with Default World Generator (port) to set the default for the users of your pack. While not intended to be used standalone, you can try the village challenge in the preset that ought to allow progression to the end via looting the villages.
