But the suggestions in earlier responses of pulling it into Inkscape gave me another idea. The original shape came from Inkscape; I should be able to make a copy of it, remove all of the interior artwork to leave just the outline, scale it up a few percent in X and Y, and then import it separately but put it on the outline layer. I may give that a shot today.
