You can do a playblast,window>playblast >options
and save the movie.
just set the shading options how you want.
shading>shade options> wireframe on shaded.
Show or hide whatever Ik's clusters etc.
If you render 3 or 4 times larger than you want
the final movie, and shrink it down in post.
the wire will look crisp and clear.

I like it better than doing a hardware render.
