Can you reverse Root Rot on pepper plants?

My Bell pepper plants were fine one day, wilted and dying the next (after an evening watering) - I strongly suspect root rot. Can this be reversed? They are just beginning to produce right now and I want to save my Bell Peppers if possible! I was thinking about digging them up and replanting with azalea mix in pots which I have on hand as I think they do prefer a more acidic soil and that soil mix has better drainage qualities. Good idea, bad, any better ideas? Any advise is welcome! Thanks in advance.
