maybe a representation like:

 super(
    'eth_getStorageAt',
    3,
    utils,
    formatters
);

would improve readability of the models.

You should add the babel conversion process as well.

Your builds have a JSON error:

(/home/travis/build/ethereum/web3.js/node_modules/lerna/lib/PackageUtilities.js:131:22)
{ [JSONError: Unexpected token } while parsing '{    "name": "web3-eth",    "namespace' in packages/web3-eth/package.json]
  name: 'JSONError',
  fileName: 'packages/web3-eth/package.json',
  exitCode: 1 }

I think babel will not be required because all "ethereum ready" platforms (browsers & node) are supporting es6. (https://kangax.github.io/compat-table/es6/)
