Realistic school choices? Am I being stupidly optimistic?

[MooPoint]

 I am an international applicant (Indian).

Mechanical engineering undergrad and I wanna apply for aerospace engineering masters. I have solid research experience. I am working on a journal paper. But I will not know anything regarding acceptance/rejection before the application deadlines. Which means I probably can't fill it in my application.

My GPA is 8.53/10.0. I am in the top 20 of my class of 132. And an institute academic merit scholar. (i.e. full scholarship based on academic performance)

Test scores: GRE general test 330/340 (164q (87th percentile); 166v (98th percentile); 5awa) TOEFL 118/120

LoRs: I will have very strong LoRs from two research project guides and one faculty adviser for non-academic research/ projects.

But the lack of publications is really stressing me out.

School list: For M.S. in Aerospace. All schools have been selected based on availability of profs/ labs in my research area of interest.

Reach: Stanford, M.I.T, Princeton, CalTech ( Is this borderline stupid on my part? Do I have any chance at all? Am I just wasting ~400 USD on these applications in total?)

Hopefuls: UMich, GeorgiaTech

Safeties: UCLA, Penn State, UToronto

Is this feasible at all? If not can you suggest a few realistic options?
