It would double the file size, you would be better off not putting the file(s) in a rar.
*PSA* Wii Redump collector's can now unscrub ISO files. So scrubbed games can now be verified. You can find the program to do this here
A second external drive with a backup of all your .rar files ins't too expensive and would put you at ease. I always keep 1-2 drives stored away with complete backups of all my important files.
Just set up recovery volumes for every part of rar file.
Recovery volume is a lot bigger than recovery record but if you don't care about the size..
Edit: Oh yeah, you want it inside of the rar file? NVM then, it's probably impossible, that's why recovery volumes exist in WinRar.
