I think you’re really underestimating how much work you’re setting yourself up for. 
Which is why I’ve never heard of anyone doing this before. I’d defo stop doing this right now if I were you.
If you’re worried about forgetting things, there are much better ways to go about it. Such as using user scripts like the Item Inspector to list all burned items and quiz yourself on them from time to time or just the Self-Study Quiz.
There is really no need to unburn anything to refresh your memory of burned items.
