Yes, it was used much rarer in the original Gunnm. However i read it couple years ago, while I still read LO now.
But the original question asked if Killy could survive Gunnm univers. And when looking at that you cannot separate LO from the original Gunnm - LO only broaden the original universe, showing how did it come to be and where is it heading. And in LO Alita displayed that she has no limits at expanding her power, mainly due to deus-ex-machina phenomenon (look at her last translated M'badi fight, she broke his hand like he was nothing!), while Killy does not enjoy such previlege.
I learned to enjoy LO for what it is and stoped geting surprised by rudiculous ideas (and creating a whip that shoots bullets by using magnetised steel dust is a crasy idea), however once I start to compare GUNNM with less over-the-top mangas, such as Blame, I cants stop raging.
