I've searched for a while, but didn't found anything about it. Is it possible to modify the super abilities of a race? And is it possible to create a new super ability?

I ask that because with the DA expansion and the race specific techs that it brings into play, I was hoping I could mod a "Super Adaptability", that could steal and/or trade any tech from any race, as in my vision something like that represents the human race better than the "Super Diplomats" it has now (We have a rich history of in a very short period of time reverse engineering techs from models).

And it's not possible to do with a super ability, would be some way that I improvise something like that? Maybe removing the super ability from the human race and modding all techs to be stolenable and tradable
