If creative thinking you mean disregard everything TOS established about the Gorn and just accept all of SNW's blatant retcon.Meh, not really. With a little creative thinking, it works perfectly fine.
TOS establishes that the Federation JUST encountered the Gorn. The Federation colonies unknowingly colonized Gorn space, so the Gorn feeling like their space had been invaded carried out the attacks in self-defense.
Kirk's Showdown with the Gorn Captain was established to be the first physical encounter the Federation had with the Gorn.
SNW retcons that the Gorn were already well known by the federation for decades and they attack human colonies because they are evil endoparasite space lizards.
