Is it possible to downgrade maps from 1.31?

Tried lots of stuff, looks like some map files can't be downgraded besides remaking them? The ones I couldn't figure out how to grab were any preplaced info or objects by map options or terrain editor as well the .w3i , upgrades(w3q), and all of the trigger files resulting in only being able to recover the terrain itself and most of the object editor.

You can recover everything you need from the MPQ. You can even discover all the models (even ones not in your listfile) by doing some code/object analysis.
The issue is going to be the natives. 1.30+ introduced many new WC3 natives, like the ability to change attackspeed, armor, etc. though code alone. There is no easy replacement for some of these. If a 1.31 map uses these, you can migrate it by removing the natives but you're going to break features. Fixing those features will take a lot of work. Depending on how heavily the map uses these as features, you might be better off starting from scratch with the terrain and objects.
