Extremophile life in Nether Lava Lakes.

What if the lava lakes in the nether had ocean like? Extremophile life like lava coral, and other nether plants could be added. Combining a vision and fire resistance potion would allow you to swim in the lava, and see all the new life. Very useful items could be harvested in the lava lakes. Mineral outcrops could rise up like stalagmites, concealed beneath the lava. Dangerous lava dwelling life could bar your path to these treasures. This would make for a challenging experience, and reward something of great value for the trouble.
