It took me a bit to figure out that the wireframe suggests taking the image from Wikidata instead of from Wikipedia. This is likely going to be a very controversial suggestion with many Wikipedians. Instead, of hiding it you should be explicit about it.
I personally, like using Wikidata images. When using Wikidata images I propose that instead of the current placeholder image, small logo or icon (P8972) of the truthy instance of (P31) claim gets shown. This leads for example to https://commons.wikimedia.org/wiki/File:Font_Awesome_5_solid_user.svg being shown as the placeholder for humans.
Given the previous experience with enwiki not liking using Wikidata item descriptions I would propose to use Wikidata items by default but allow Wikipedia to override the images if a particular Wikipedia prefers a different image. If that ability to override the default is build in from the beginning maybe we can prevent conflict from arrising.
When it comes to redirects as in this case, I would want in case the redirect has a sitelink to redirect from Wikidata and that Wikidata item has an image, that it's image gets preferred over the image of the Wikidata item that's linked to the article.
