Can we programme our own modding tools?

I have an idea:

Somewhere within the R:TW programme file is a snippet of code that extracts all of our precious .pak files so that the game may use their contents.

I personally do not yet possess the skill or experience required to locate, reverse and utilise this code by plugging it into a simple decompression software, but I'm sure someone here must be capable of this feat.

Why must we wait for Activistion to release any modding tools - which may or may not happen - if we can programme our own?
