Maybe PowerDeleteSuite works for you

I used power delete suite. It also let's you save a copy of all the original comments with their permalinks in a CSV.

You may need to run it more than once. I think due to rate limiting from reddit for many edits like this.

I've done something similar using the Violent Monkey extension for Firefox, RES (to load all of my comments on a single page), and a script I found on Greasy Fork. That script was supposed to replace comments with gibberish, THEN delete everything, but I hacked the deletion part away and changed the gibberish edit for a custom text. Let me try and fix it so I can share it with you (unless someone with a better solution shows up).
