Nope, you won't be able to access the DB while it's in recovery, at all, DAC or no DAC. How do you know there's corruption? Got the error messages? Or are you just guessing there is some?
If you restart SQL, the recovery starts over from the beginning.
Wait it out (check the error log for progress reports) or restore from backup.
