Yep. My 6-cylinder SE has vertical adjustments on the fan shroud, where the top clips attach. As my front mounts sag (pretty routinely) I adjust the shroud a bit to keep the fan centered. You might be able to do that to make it driveable until you can replace the front mounts.
Remember of course that the angle change may put additional angular load on the front flex disc, and maybe even change the middle u-joint working angle a bit. So, might be a good idea to install the front mounts pretty soon.
