Collection-ary. Not monsters...but other stuff.

I like Star Ocean 3.
I like Disgaea for the PsP.
They So3 has a wonderful battle trophy system, that takes note when you finished an accomplishment, and records it as completed.
Disgaea on the PsP has an utterly meaningless collection system that made you feel good the more you collected stuff.
Unfortunately, (maybe because I suck at sifting through the available scripts here) the closest thing to either of these...is a bestiary.

It would make me happy if there was one who could develop scripts that are capable of recording random feats...ie: "you hit for exactly 7777 damage in battle!" "Finished the battle in 1 action!" "Reached level 99" "Gained more than 3 levels in 1 battle!"
When I think about it, I imagine it would require different script for every feat...but... its an idea.

Perhaps I could get feedback on this?

All I can say is that it is pretty simple. You mostly just need a few counters and storing some variables when a battle starts. I suggest you put a list together of which achievements you want since each requires a slightly different script. That way it can be made like one script.
