Replace Gravel in the Nether [1.10.2]

[Villfuk02]

I know there must be, but i havent found any way how to replace all the gravel in nether with my own blocks, when nether is generated. What i'm using now is this:

 

for(int i = 0; i < 600; i++)	{
			BlockPos pos = new BlockPos(chunkX*16 + random.nextInt(16), 63 + random.nextInt(3), (chunkZ*16) + random.nextInt(16));
			new WorldGenMinable(ModBlocks.nethersand.getDefaultState(), 32, BlockMatcher.forBlock(Blocks.GRAVEL)).generate(world, random, pos);
		}

Btw, i mean BETTER way and it would be cool if it didn't cause any block updates, so the blocks would still float until something updates them

Thanks
