Guide may be out of date.
I did not originally make the mod, just wanted to be helpful providing instructions to set it up.
It may not work anymore or you may face the usual source engine jank.
Get the Files
To make the maps work in coop, you'll need custom files.
Download[drive.google.com]
Only the person playing Atlas (hosting/inviting) needs the files.

Once you've download the zip. you'll need to copy the files from the "maps" folder to your "portal2_dlc2/maps/" folder.
Windows path:
C:\Program Files (x86)\Steam\steamapps\common\Portal 2\portal2_dlc2\maps


Putting it in dlc2 makes it easier to restore the commentary back to default if you want to, by removing the files.
Play the Maps
Get into a coop session, where you are Atlas.
Wait until the current map has loaded and you can walk around.

First, enter commentary 1 to enable the custom content.
Then, enter changelevel mapname, where mapname is the map you want to go to.

Good maps to start from:
sp_a1_intro2 - Skip the buggy container ride
sp_a2_intro - down the incinerator
Known Issues
Due to it being a singleplayer campaign, doors will close if one person passes them, so have sv_cheats 1 on to noclip through.

The game may sometimes crash or return to the menu.

Remember to set commentary 0 before starting a new multiplayer session or P-body will get an error message like #Valve_hidden_game. If it continues to not work, restart your game.

Some entity logic is broken and you may get stuck, in which case you may want to skip to the next level.

Wheatley turn-around, solution:
ent_fire @glados runscriptcode "sp_a1_intro7_TurnAroundNow()"

If you want the full immersive experience, do change_portalgun_linkage_id 0 to control the same set of portals as Chell (this may fix some issues).

This is a rewrite of this guide to be a bit more easier to follow. This mod isn't my own, but I enjoy it very much.

For those who are stuck in the loading screen and/or not being able to spawn at all in Laser Catapult (sp_a4_laser_catapult), I have a temporary fix:

Right click on Portal 2 in your library and click "Browse local files". Then, in the opened file explorer window, navigate to portal2_dlc2/maps (assuming that is where you installed the mod), and open sp_a4_laser_catapult_commentary.txt with a text editor.

Press Ctrl+F (or Command+F if you're on Mac) and type 2061. Click "Find" to jump to that number, and look for InstanceAuto24-blue_dropper-initial_spawn.

If you found it, you may have noticed that the string isn't fully wrapped in quotation marks. Add the missing quotation mark at the end of the string, and save the file by doing Ctrl+S (or Command+S on Mac). The map should work now when both players fully load in.

1. No it wouldn't

2. Switch isn't cross play with PC.

Since Portal 2 and Portal is on Nintendo Switch, (even though i dont have it) DO NOT USE MODS WITH A SWITCH PLAYER. I'm pretty sure it would ban their switch

This works in split screen, but when going through a loading zone both players can't move. You can solve this with a quick command but you will have to run it every time you go through a loading zone. First, go through the elevator to a new area, then once you load in, don't move either side and immediately open the dev console to prevent a crash. Once you are in the dev console look in the top right and look at what map you are in. Just run "changelevel <level you saw in the top right>" and the level will reload with both players in-bounds.
