Yes.

You'd have to make a nice arrowhead that fits on the arpeggio symbol.
That's probably the hardest thing.  I think that it should even
contain a small piece of the squiggly line (about half a squiggle),
ending in a straight where the arrow head fits.

You can probably tell the arpeggio symbol whether to add what arrowhead by
setting an arpeggio grob property.
