It might be possible to run more emulators on Win32s by the help of Tos2Win.
In essence, the Atari ST was the spritiual predecessor of a Win 3.x PC, after all.:
TOS consisted of CP/M 68k core and GEM environment, which share some similarities with DOS+Windows.
CP/M 68k, being CP/M, used a similar design like DOS, while GEM had similar APIs (VDI vs GDI).
This makes me wonder if it is possible to run, say, an ancient Mac 68k emulator on Tos2Win.
Since both use the Motorola 68000 CPU, there should be no "emulation inside emulation" speed penalty.
Edit: Some emulators for TOS/GEM are listed at this Atari page: https://www.atariuptodate.de/en/emulators/
