Those plants are perfectly recoverable, the trick is going to be maximizing soil removal while minimizing root damage in teh process. I'd do it sooner rather than later.
I don't know where the OP lives, but if you're east of the Mississippi and feelin' cheap, go to Agway for your medium- I've been happily growing in their bagged composted manure and humus mix, cut by 30% with perlite, ever since I found the stuff. It holds ROCK steady pH at 6.8 and drains fabulously when cut with lightener. It's $2.50 for 40#... happy happy joy joy...
