Very nice!
I would suggest testing on a c5.large. t2 and t3 have shared CPUs, so
they have less consistent boot time. c5.large is about the same cost as
t3.large, but will have far more consistent performance.

Thank you for working on this!
Have you confirmed that with the optimizations, you can boot without
needing an initramfs?
