Combine with existing eslintrc?

[tupton]

I have a project that uses both jscs and eslint, and I'd like to merge that into one config. I was hoping something like polyjuice --jscs path/to/jscsrc --eslint path/to/eslintrc > eslintrc.json would combine the two, but it seems to ignore the eslint config. I understand that option is when converting to jscs or jshint, but it'd be nifty to be able to merge into one unified eslint config.
