You mean to produce something like this?

That can be done with LSQMAN - http://xray.bmc.uu.se/usf/lsqman_man.html#S65
Of course, there are lots of other interesting metrics and plots to assess
structural differences between two models -

One of my favourite ones is the CD plot, for comparing multiple models, which
looks a bit like a gel: http://xray.bmc.uu.se/usf/pics/cdplot_1ldn.gif
For other options, see http://xray.bmc.uu.se/usf/lsqman_man.html#H19
