This has been possible for a very long time, as a side-effect of enabling browser.ctrlTab.previews in about:config
Glad to see they are paying more attention to this though.
Thousands of people have requested that feature for Chrome. To this day there hasn't been (or I haven't found) an official answer and the only way to do it is to use an extension, using an alternative keybind as extensions aren't allowed to interact with ctrl-tab.
Chrome doesn't add settings for things when extensions can do the job because doing so adds to our support burden and slows further development - it's better to appeal to fewer people and have a simpler and easier/faster-to-maintain product than to appeal to more with higher maintenance complexity.
