Not really. Nia was a Anti-Spiral creation and ran out of power when there were no more Anti-Spirals.
Also look at the extent of crazy shit Simon did for her up until that point. Can you imagine how much more things would escalate if she stayed around?
It's even implied in the end Simon could have found a way to save or even revive her, as Spiral Energy can literally make the impossible possible. But that kind of going against the natural order would just end up leading Simon into full Spiral Nemesis path, endangering the whole universe and proving the Anti-Spirals right all along. That's why he ljust accepts Nia's death and steps down from pilotiong reality warping giant robots.
I really can't understand why some people want the show to ignore its own conclusion just to have a happier ending and TTGL ending isn't even sad, can't you faggots take something even a bit bittersweet?
