I mean... I guess? Season 2 also had a giant kaiju monster as a final battle funnily enough.

Mecha suits were already a thing so a giant one doesn't seem too out of the question, just like how sato basically invented airplanes for the sole purpose of Amon's revolution.

Plus it makes sense that she was conquering all those cities and stealing their platinum (along with other resources) to make a suit.

I don't know how else the writers could have done a final battle, or what else they could have done besides giving kuvira her own the iron giant.
