Migrating Parabola, GuixSD, PureOS, LibertyBSD, Trisquel to arm64?

I have HBSD-arm64, ArchLinuxARM64, Gentoo-arm64 installers to observe if we should migrate our future devel to arm64, but first of all I need to order an arm64 laptop like Libreboot’ed Chromemook to observe this.
If optimistic I will start and default my IceOS project freeing HBSD at arm64 platform then I will try to help to port the well known GNU free systems like Parabola, GuixSD, PureOS, LibertyBSD, Trisquel to arm64.
The first task to be completed is to make desktop live USBs for arm64 platform. :)
