I really can't answer with absolute certainty, I sure only DE can. I can only assume that since you've overwritten the pc save you lost everything that was inside it... But prime gaming stuff might be something that DE could have kept track of, maybe in the future they'll make them available for people in your situation? Maybe it's wishful thinking, but who knows. Again, take everything with a pinch of salt, you're questions are a little bit more technical than the stuff that was explained officially by DE. Maybe try contacting DE customer service?

If you set your pc account as primary you'll lose the console account progress, vice versa if you set the console one as primary.
