Topic: Pacman over P2P with Pacman2pacman
As Hyperbola it's an LTS release, with not as much packages as bigger distros, I suggest trying pacman2pacman.

The PKGBUILD requires gettext-tiny to be added as a dependency, sha256 sums and the systemd recommendation hints on the .install file removed. And the mentiones *.sig files for pacman db updates are not needed I think. Probably it could be easily adapted to Hyperbola's pacman.
The Bash script calls pacman to fetch the packages over Bittorrent with the aid of a locally running Transmission daemon. If the P2P daemon isn't able to fetch the packages because of a random reason, it falls back to HTTPS over a few seconds. That could help to reduce the strain on Hyperbola's HTTPS repos over time.
