After finishing my replay of TW3 with both Heart of Stone and Blood&Wine in NG+... I have to wonder, is there a way to import the save again to start another NG+?
Normally, the game only allows a NG+ using a normal save, you can't use a NG+ save. Is there a way to bypass that restriction? I realize that it wouldn't be challenging or anything, but plough that.

Second run is the last one, so far there is no NG++ and yet no way to load a NG+ savegame for another NG+ - but of course the savegame must contain a kind of switch that indicates "i am ng+" might be changed somehow. But I'm not aware of a tool nor the adress of that switch - the problem is - there is a lot of stuff that is levelled manually to match the NG+, not all items do autoscale, especially the witcher gear doesnt ...

For me the NG+ is way too easy with all the stuff in inventory, ability points etc ...

On PC we have the Debug Console at hand , you could recreate your NG+ stats on a new fresh run with no problem.
