Some apis have changed compared to the Firefox OS apps since we're based on the work done for KaiOS 3.x

There is some documentation here about the changes.

Is it possible for a JS wrapper/binder bring compability to these old apps and their old API calls?

In most cases yes (one exception is when your app provides activities or uses system messages, since they now rely on a service worker event). You also need to adapt the manifest to the standard PWA format, but that part is really easy.
