Hi,
I take it you want to want to create something like TrueOS (which is basically FreeBSD for mortals).
I personally think MINIX is nowhere near mature enough to make such a proposal meaningful. There are simply too many missing pieces (no USB on x86, no SMP, no 64 bit support, no kernel threads, no standard sound API, lackluster hardware support...) to make MINIX a viable everyday desktop system. We can't compete with Ubuntu by a long shot.
For example, if I were to install MINIX on my freshly mounted Ryzen-based computer I would have to give up on 28 GiB of RAM out of 32, 7 processor cores out of 8, the M.2 SSD, Bluetooth and Wi-Fi connectivity, my USB keyboard and mouse... I'm not even sure I could SSH into it, I'd probably need to use the serial port to interact with it (and I specifically picked a motherboard with one). I couldn't even install it with the installation CD since the computer doesn't have a CD drive.
That doesn't mean those issues can't be solved with enough hard work, but the fact remains that if I want to install MINIX 3 right now on a real computer, with decent hardware support and without wasting 90%+ of its computing power, I would dust off my Athlon 64 rig from 15 years ago. Running an everyday desktop operating system inside a virtual machine to work around that defeats the point of "everyday desktop operating system".
The situation is improving, for example the modern networking stack just got merged. However, consumer hardware is improving at a faster rate. MINIX for me is fundamentally a hacker's operating system, in a good way: simple to get into, easy to tinker with and improve, but it ain't no Ubuntu.
