Google already works like this in browsers that support it (most modern ones). The ad is linked to the destination URL with no redirects through any advertiser-controlled domain. A third-party tracking URL can be specified, and it will be pinged in the background using the browser's sendBeacon() function. Any redirects in response to the ping don't affect what webpage the browser displays, so they can't be used to hijack the click.
