Well, I regularly get 1 MByte/s from nearby mirrors. Call me
undemanding, but I think that's a realistic value for "fast".

*splutter*. You obviously haven't seen setup.exe's source code, and
you're forgetting that any such solution also needs to be integrated
into the UI, most interestingly, the progress screen, which is
currently designed for downloading one package at a time. Parallel
downloading would be nice to have, but it's nowhere near the top of
the list of potential setup.exe improvements.

Meanwhile, you could always implement your scheme as a script that
downloads into a local directory and installs from there.
