new biome with new dungeon and new villages: caribbean islands

So what can i begin with ? This idea is a bit complex so please read until the end.

Biome look:

+not so deep ocean with lighter water, (you know caribbean water) with similiar look to jungle biomes on land

+a lot of tiny islands with sand, stone and grass. acacialike trees made with jungle wood and leaves.

+often boats at the beaches (no rideable boats)

+sometimes hidden chests with gold nuggets

new village type:

+buildings: round huts with hayblocks on top and built with jungle wood, huts connected with planks.

+sometimes whole village on the island, sometimes half on island, half in water.

+cheaper treasure map trades

dungeon:

+shipwrack at beach

+skeleton/zombie spawner

+1 chest: gold nuggets

+item frame with treasure map

+can't be located using another treasure map

Tell me, what u think about this, I really like the caribbean and it would be a really nice addition to the game.
