I'd be ok with it if it's possible to use all the insights and software from after that, we'd just be constrained by the hardware - the Amiga 4000, Apple Mac Quadra 840av 128 MB or a Pentium 66 MHz or the 486 DX2-66 with 64 MB ram.

Can't we achieve something like this now with microcontrollers like ESP32 or RP2040?

This project runs a ca. 1990 scientific workstation (not just a PC) on an RP2040:
