Long shot? Yes. But not impossible.

The first step you'd need is a reliable way to deliver DNSSEC records to browsers, which does not currently exist. So I feel like you're missing at least a step 0, if not a step -1 (of getting ~anybody to actually sign zones.)

What's the incentive for individual sites or browsers to do this?
From the site's perspective, they're going to need to have a WebPKI certificate for the foreseeable future, basically until there is no appreciable population of WebPKI-only clients, which is years in the future. So DANE is strictly more work.
From the browser's perspective, very few sites actually support DANE, and the current situation is satisfactory, so why go to any additional effort?
In order for technologies to get wide deployment, they usually need to be valuable to individual ecosystem actors at the margin, i.e., they have to get value by deploying them today. Even stipulating that an eventual DANE-only system is better, it doesn't provide any benefit in the near term, so it's very hard to get deployment.
