I've been mulling something very similar, though your idea is on a much grander scale. I'm designing a session reviewer that links back into the PT database and shows the realtime stats of your opponents. For instance, if it's relatively early in your session, and you only have 20 hands on your opponent, that's how many hands worth of stats that you'll have on that opponent.

Because of that feature, I don't think that I can really do it online.

Was planning on doing this in C# in VS2005

edit: also, I feel that "playing along" is much, MUCH more valuable in reviewing a session than just reading a prettied up hand history. Adding a feature that allows comments on every action junction would be valuable.
