That would be fully RAW compliant 👍

All of those peasants will need to perform a grapple check with a +0 bonus.

C'mon, lets not dictate who's fun based on a shameless attempt to bend D&D rules and physics into a pretzel. You already gave up on physics at the moment you decided a line of people can pass an object instantly. Going from 100% RAW no physics to 100% physics RAW be damned is kind of a smartass move. I honestly doubt people would even be trying this in real games if not for the meme, because how do you even organize a perfect line of peasants in the middle of a combat encounter?

There's a lot of fun things you can do without stretching believability to the breaking point. One of my favorite Pathfinder characters was an aarakocra barbarian that used enhanced carry capacity to wrestle enemies into the air and throw them at each other. No need to selectively reinvent physics to make it work.
