Nah, I'd more liken what you want to do as trying to figure out what kind of plastic the Risk play pieces are made of... :P
We've already got epic boss damage formulas which are nice for the geeks and uninteresting for 99% of the player base.
You want to reverse-engineer damage formulas for way less relevant monsters, also with zero guarantee that Gree doesn't tweak/change the values at some point in time. That's just a lot of investment for near zero use.
