That's definitely an interesting approach, and it'd be neat to see an Astronomer as opposed to an Astrologist. However, we'd still need to know how much the Eorzeans know about their universe and how the stars actually work. For example - the blue giant in your blurb. Would they know that there are stars out there that are, in actuality, bigger then Hydaelyn's sun?
In fact, can we fully say that the heavens in the FFXIV universe work like ours? For all we know, it could follow the Celestial Spheres model or something completely different from our Heliocentric system sitting on the arm of a massive galaxy. After all, somehow the Ishgardians are using the movements of the stars to accurately tell when the Dravanian Hordes are going to attack.
I still think it'd be a fun thing to play - using a scientific approach - but I'd keep an eye on the lore so that it fits the "science" as presented in the game.
