No bans yet isn't the same as good, an account can be silently shadowbanned or trust-limited and still look fine to you. So first confirm each one isn't shadowbanned: check the profile logged out or hit its about.json, and drop a comment in an active sub then view it from another account, if only you can see it, it's filtered. r/ShadowBan's bot confirms it outright too. Past that, a genuinely good account is one whose comments actually stick and pick up the odd upvote from real users, not just post successfully, and that can comment in mid-size subs without instant AutoMod removal.
The bigger thing before you scale is that these came off one creator, so the risk isn't each account alone, it's that they're linked. If they were made on the same IP, fingerprint or email pattern, they share a signature, and the moment you scale and act in volume is exactly when Reddit connects them and bans the batch together. So your approach of commenting and letting them settle is right, just add the logged-out check and make sure each account has its own clean IP and fingerprint. And ramp slowly instead of going big at once, that way if a signal is off you lose a handful, not the whole set.
Best,
