New hand crafted 1.7 themed island is here! The savannah island. Sorry for bad picture quality, i have been lazy to install 1.6 shaders.

Also this plug and play island is a little bit more difficult to install. The steps are:
Unzip the schematic, drop it in [your server]/plugins/worldedit/schematics.

Type //schem load savannah on your server.

Find ocean with plenty space to your north, northeast, northwest (island is very large).

Type //paste -a at water level.

Fly over the savannah, where ravine is covered with wool, and type /replacenear 50 wool air. That is cave mapping, and underground mineshaft. Wool does not allow ocean to fill them on paste.

Type //sel poly, tag point at edge of island with wool, hit it with wooden axe, then fly around, keep right clicking blocks on edge of cliff, until you come back to the wool from other side, and type //setbiome desert. Remove the wool tag. This will bring correct feel of savannah biome from 1.7 (no rain, yellow grass).

Spawn bunch of villagers in village, bunch of horses pigs cows around the island, and job is done.

Enjoy!
