I haven't looked at your code, but for it to be included you need the following:

1. Must be internationalized.
2. Must have a help file.
3. Code must be documented with POD.
4. Code must conform to WebGUI Best Practices.
5. And finally once all that is done a Plain Black staffer will need to vet it for security and performance.

I've stopped working on this in favor of the AssetReport wobject, which is (IMHO) a much more generally useful implementation of this idea.

If folks still want this, feel free to implement the things JT lays out as needed before it can be considered for core inclusion.
