Could use `copy` or `copy-simple` [icons](https://phosphoricons.com/?q=%22copy%22) as base. Also `selection-background` and `selection-foreground` [icons](https://phosphoricons.com/?q=%22selection+ground%22) are related to this so could use that but those still indicate more for selection when these icons should emphasize that they move the object/element it self.
