Three things.

First, I'm not sure this solution is actually necessary at all.

Second, endorsing sounds like a lot of tedious work.

Third, the system as described has a number of issues. I would modify it in the following ways:

1. Number of endorsements is proportional to story rank, and changes as the story rank changes. After story rank 60, no endorsement is required.

2. Number of pending comments allowed for a given user is proportional to his or her karma. Users with karma of 1 should have 1, users with karma 1000 should have more, perhaps 5-10.

3. Unendorsed comments appear visually distinct from hidden posts and down-voted posts. Perhaps a shaded background?

4. If a user has exhausted his or her unendorsed comments pool in this 24-hour period, they should be informed of this fact where the new comment text area normally is.
