You could sleeve the holes BUT you'd be losing a significant amount of the original tapered surface which is what retains the wheel - the sleeve would just be filling the hole.

The wheels should center properly on the hub since they are "Mopar" wheels. I wouldn't worry too much about the elongated holes, they don't look that bad - would probably look worse after the repairs !! I'd just make sure when installing them that they are snugged down gradually and that they center on the taper of the nuts.
