Implementing Lightroom Classic, Lightroom, Lightroom Mobile/Environment to achieve storage goals

Hey all, I would like to discuss how to achieve the following goal with syncing/editing/storage across the "Lightroom Environment"/Cloud and my local storage. I would like to:

1) Have my local storage(hard drive) be the main hub from which I am bringing images into Lightroom

2) Be able to delete images while editing in Lightroom and have them be removed from local storage as well. ** I have started using Lightroom Classic for these reasons.** Furthermore,

3) I would like to sync my images and edits to those images to the Cloud/Lightroom Environment so that I may access my edited images mainly from my mobile phone (Lightroom Mobile) **noted that you may sync collections (only as smart previews) from Lightroom Classic to Creative Cloud**.

THIS IS WHERE MY MAIN QUESTION IS.

4) I would like to use "the cloud"/cloud as a cloud storage/backup for the full sized, edited images, not just smart previews. Do I need to bring Lightroom CC into this to achieve this?

5) I do not want Lightroom CC to store its own set of originals on my local storage (is this possible, as I don't want to take up essentially twice the storage that I am currently using?) If so, how do I go about implementing Lightroom CC with all of this information/goals in mind.
