"Okay,
So all my folders, apps, music, pictures lalalala copy with migration assistant?"
Yes, that should work well.
You don't need to use CCC to "reverse clone", because migration assistant will do its thing and "pull" all the relevant files from your cloned copy, leaving behind that which isn't needed.
Once you're all set up with the new MBA, you can _again_ use CCC to create a bootable clone from your _new_ setup.
