No idea how the tech works, but I know back in the day CrossOver did macOS app wrappers for Windows programs. Is it not possible to make a 64 bit "wrapper" for a 32-bit macOS app to then run 32-bit apps on Catalina and above?
Got a tip for us?

64-bit "wrappers" for 32-bit apps?

Sounds like a good undergrad project— make a transpiler. Completely possible. I think the main issue would be supporting defunct APIs. Still, doable with enough undergrads.
No-one cared about 32-bit apps https://forums.macrumors.com/threads/still-can-run-32-bit-apps-in-catalina.2205908/
A 32bit to 64bit Rosetta should be possible, but didn't Apple also deprecate or remove a lot of system APIs during that transition?
