How to run other registered grunt tasks within a grunt plugin?

I'm working on writing a grunt plugin that will help with a build process I use quite frequently. What I usually end up doing is copying/pasting my GruntFile from project to project, but I think it might be a bit more useful putting it into a plugin. The tasks that I use for this build process are usually grunt tasks such as jshint, copy, cssmin, less, and uglify amongst others. I think I could clean up my Gruntfile.js file a ton if I could create a plugin that just took in some configuration and ran all of those tasks.

My current setup is usually something like this:

grunt.initConfig({
  jshint: {/* ... */},
  copy: {/* ... */},
  less: {/* ... */},
  cssmin: {/* ... */},
  uglify: {/* ... */}
});

  // Load and Register tasks...

but I would like to reduce the initConfig to something like this:

grunt.initConfig({
  build: {
    dev: {
      paths: {
        public: 'public',
        source: 'source',
        bower: 'bower_components'
      },
      options: {
        pretty: true,
        minify: false
      }
    }
  }
});

Is this something that can be done from within a grunt plugin?

EDIT: I found something similar to what I was looking for, but it doesn't seem all that elegant, especially with all of the configurations I'll need to manually setup, but maybe it's worth it.
