I implied some sort of application that would take a 32-bit macOS app and turn it into a 64-bit app suitable for delivering to customers in the interim. But I gave solutions only for a sophisticated user to run 32-bit applications from Catalina (or so) desktop.

The app's program would be moved and replaced with something else that uses some sort of hyper-something to catch the INTs or that will use ptrace() as a debugger would. In the latter case the INTs might need to be translated statically by the converter. I have not made a modern debugger, tracer or hyper-thing, so I'm just guessing.

You can run an application on a client OS in a window on the host. So, if you have an older macOS running on a virtual machine that can run your app, you can set things up so that you can double-click on your desktop and run a 32-bit app.

For example, instead of upgrading to Catalina on your old Mac Mini, get a new Mac Mini with Catalina and remote desktop into the old Mac Mini. Or have a Mac that is running several virtual machines you can remote into (use memory ballooning to share it well). The Apple EULA has constraints, but I think this is OK.

You can readily run a single app in a window for a linux server using several programs such as nomachine and (I think) xpra. But I don't know about macOS. Maybe you can make a single-window app full screen and adjust the size of the client window. I haven't tried this.
