I don't think Agatio can do that w/o you losing your engraves ( i remember him saying something like that but im not 100% sure)
As for ds in ns, -1 for removing it, -1 to making it not account stashable +/-1 on making them untradeable, i'm kinda neutral about that part but i honestly don't feel like the price has dropped very much or the market is overflooded with them but then again i can't say i look out for them overly much.
