Since you put it this way, i would say no. Ranier is a big, serious mountain. It is not a "glacier walk". Expect steep slopes, ice, big crevasses, altitude issues and serious consequnces if something goes wrong.
If you are really wanting to solo a big volcano, Mt. Baker woul be a better choice - Coleman-Deming route. Of course, people die every year on that route, too, mostly from falling on a steep icey slope into a crevasse.
