Ok, then what alternatives exist in 1986?

Happy to use hindsight, so you may wish to say "use Windows PE format".

I would say the fundamental thing is that the MSDOS filesystem code is stable, so any solution needs to eventually call 16-bit MSDOS.

DPMI hasn't been invented yet, but we can invent it exactly as-is, or have a stop-gap measure. So long as the stop-gap measure is divorced from the executable itself, it can be changed with impunity.

People still want to run 16-bit MSDOS software, and that isn't changing.

I'm not a fan of DLLs, so I'd prefer not to go on that path.

The C language is taking off, so I'd like to see a C library provided to executables.

What sensible suggestions exist in 1986? What about 1990? No need to be first to market either. Possibly something that academia would approve of.
