Sure it could work if kill trackers are account based. For example. You have x roll of x weapon on that roll you have on a character you pull the same roll from collections kill tracker remains. It's essentially a clone of what you already have. But say you accidentally dismantled this way you also don't lose that tracker you don't waste space holding on to it and can't only re acquire what you've had nothing advantageous. Just no loss for the player.
