At that point you might as well just write an AArch64 emulator in uxn and run Chrome that way. It wouldn't be much slower than the "native" build.

I'm pretty sure you could fit a blockchain into 64kb of memory too. Not sure why you'd want to do such a thing though except for amusement (the reason a lot of us do anything at all).
