Not entirely sure this is the correct location for this post so please feel free to move it / redirect me to where this should go. Basically my boss wants to use the idea behind manifest json to publish a web app to the iOS app store, and I am of course tasked with finding out if this is even possible (which I'm pretty positive it is not). There are a few different reasons why we are trying to figure it out, replacing a legacy app, being able to update the application without re-submitting to the app store and having to wait for the week long review period, and lastly would be ease of development with a single code-base.
If anyone could simply verify if it is possible to use a manifest or progressive web app in this way that would be great, he is trying to avoid having to go the native or phonegap-esque route if at all possible.
Your information is mixed/outdated, so it might help to clear things up first, before deciding on a path forward.
Web apps (app installed via the web) today are not done via the store. You can't use the store and avoid the store at the same time.

A 'store' app would require re-submission when updated, of course. The wait period is down to 2 says now, typically. If you want to avoid those outright, don't use the store.
