For the sake of how many you want to daisy chain disregarding the processing power and other resources needed and what is directly availible now (So nothing currently publicly released like XWine1), using Virtual Machines would be paramount to puling it off.
Windows PC --> Linux (WSL/Virtual VM) --> 4 Windows PC (Virtual Box VM) + Linux (Virtualbox VM) -> Android (Bluestacks on Windows VM 1 and 2), 2 Xenia instances on Windows VM 3, at minimum 15(!!!) Cmeu instances on Windows VM 4 (14 of which are becuase of Virtual Console across Wii U and using vWii to avoid another chain with Dolphin but you can to also use Virtual Console releases to emulate the same systems the Wii VC shares with WIIU VC if you want to be extra about it) , and Four instances of RPCS3 On Linux VM 2 --> Switch (The forks of the two dead emulators on Bluestacks on Windows VM), 1 Xenia instance using Fusion for OG Xbox and the other running a XB360 game, One of every console covered by Wii and Wii U VC across Wii U and vWii, plus one Wii U game running and a Wii Game running through vWii on Windows VM 4 and MultiMan for PS1, PS2 and PSP on the three RPCS3 instances and one PS3 Game on the fouth instance on Linux VM 2 -> GameCube -> GBA -> NES (homebrew on Switch emulator on Bluestacks on Windows VM 1)
The amount of resources needed just to run all this at once will be very signicant and will be better off on literally anything else, especially since the later gen emulators and the VMs will be what will take the lionshare of resources.
