Package.json and bower.json in CoffeeScript?

I would like to write my package.json

and bower.json

in CoffeeScript.

I am using Gulp, but I am very new to writing Gulp tasks.

How do I get NPM and Bower to use the CoffeeScript configuration?

PS I was unable to find a way to override the path to the Bower and NPM settings, so it seems to me that I need to save the compiled JSON files to disk. :( Is there a way to avoid this and pass JSONs to commands npm

and bower

without reading / writing the disk?
