Rooting about in the chrome://flags screen I found something interesting in an included JS file :

/**
 * Invoked when the selection of a multi-value choice is changed to the
 * specified index.
 * @param {HTMLElement} node The node for the experiment being changed.
 * @param {number} index The index of the option that was selected.
 */
function handleSelectChoiceExperiment(node, index) {
  // Tell the C++ FlagsDOMHandler to enable the selected choice.
  chrome.send('enableFlagsExperiment',
              [String(node.internal_name) + '@' + index, 'true']);
  requestFlagsExperimentsData();
}

chrome.send is indeed a valid method,

Here is another snippet form the same file (chrome://flags/flags.js)

/**
 * Asks the C++ FlagsDOMHandler to restart the browser (restoring tabs).
 */
function restartBrowser() {
  chrome.send('restartBrowser');
}

Manually calling chrome.send ('restartBroswer') did indeed restart the browser.

I think this provides all the facilities you need to automate the setting of the flags, you will need to trawl through the chrome://flags source to find the flags you need and then set up the appropriate chrome.send calls.
