Can we run an A/B test around 5:4 images in article pages?

[CDicksonG]

There appears to be an ambition from editorial to switch to 5:4 images on the article pages ahead of the new fronts relaunch. If this work is set to commence soon it would be nice to get ahead of any of the effects this would have on behaviour of our users. Could we set up a test to look at the change and what it would do to the audience.

I think we would need buy in from stakeholders as well as conversations with D&I and the audience team around what metrics they would like to monitor.
