Yeah, you can just replace the studs. If you haven't took them off then how do you know they are crossthreaded? I don't think the studs are going to break just by taking them off and even if the did you can still replace them. When you go to replace them take the wheel off. Hammer the old one out through the back. Put the new one on the hole straight and with the splines lining up. Put a bunch of washers on the front and the lugnut. Tighten the lugnut up by hand to pull the stud all the way in.
