Can I keep the same listing but change the package it provides?

Yes, you can change the packages that are linked to your listing. First, make sure that you’ve uploaded the new package and, if the listing is public, that the package has passed the security review.

On the Publishing page in the Partner Community, navigate to the Packages tab and find the package associated with the listing that you want to update. Click Edit Listing to open the publishing console. If you’re updating an app, you can add a package on the App tab. If you’re updating a component, add it on the Component tab.
