Infinity SL 30 replacement drivers

I have a pair of Infinity SL 30’s with both tweeters fried, and one bass driver damaged. The boxes are in really good shape and didn’t want to throw them out if it was worth getting some new drivers. I would like to replace them with a set of new tweeters and bass drivers that wont break the bank and will sound as good if not better. I am also thinking of modding or replacing the crossover. I would greatly appreciate anyone’s feedback.
