Yes: we are doing this for the galley in LaTeX3. You just set the line
length to be shorter than the surroundings. Using e-TeX, a simple
example is something like:

  \parshape 1 0 pt \dimexpr\linewidth - <right margin>\relax\relax

Depending on your exact requirements, you might want to do some
calculation with \hsize and \@totalleftmargin (assuming LaTeX2e). (My
example is rather simplistic.)
