Not with copy-paste (limited API for that, too, outside of adding text to the clipboard), but it could be done by having the user highlight the number prior to running the gadget. The catch is that the copies it creates would be vectors, rather than text. You couldn't go back and edit them as text at that point.
That said, VCarve/Aspire have an array copy function that will create rotated copies of whatever you've selected. That may be what you're asking for by this point.
It will be nice to see some updates to the Lua API, should Vectric ever decide to give it a little TLC.
