Alright! After quite an ordeal including replacing memory modules in my 486 and eventually building a lab vm, I got to show off true multitasking on top of DOS! This was accomplished using a fairly obscure piece of software called DesqView originating all the way back from 1985, while the version I used was from 1996 and built to work with the QEMM8 memory manager.
We had a lot of fun exploration on stream seeing what would work and even ran graphical programs side be side by text mode things, with the full ability to swap between them. There was some palette corruption during the swapping that kinda just adds a neat look to it all. Also some truly memorable midi crimes occurred :)

DESQView unfortunately still exhibits some significant memory corruption. I went as far as replacing the RAM in the system with a configuration the motherboard explicitly supports (32MB from 16+16), as well as disabling all CPU caching incase it was a timing problem - but it does not seem to help. Part of actually working with real retro hardware I guess!
I will have to dump the systems drive and see about getting things from there imported under a VM instead, it looks promising on both counts initially but I don’t know how true to hardware 86Box is on this level - so we’ll see. Still very much want to get to explore multitasking on DOS.

Hey women in aviation, any recommendations for a reliable and clear to read watch for flying? Preferably non-huge, and the batteries should last - I don’t care about smart functions.
