Can a character wear both Chain mail and Leather to get a higher AC and to fool an enemy?


Background:
I am reading the anime book "Goblin Slayer", the light novel not the comic.

In it the main character wears leather armor over plate or chain to both stack his AC and to confuse his (not very intelligent) enemies into hitting where leather is vulnerable but plate or chain is not.

Question:
In dnd 5th edition, can one wear multiple types of armor and get an AC stack? Can it confuse weak foes like goblins?

Notes:
Here are answers that don’t speak to this question:

  • Can a chain shirt be concealed under normal clothing? (this is about concealed, I’m asking about stacked)
  • Stacking multiple types of armor (this is not dnd 5e centric)
  • Can you wear a Mithral Chain over Snakeskin Tunic and have their effect stack? (this is pathfinder)

Please, if you are going to down-vote, say why in the comments. If I don’t know what I did wrong, it is literally impossible for me to willfully act better and change that thing. It might happen by accident, but the universe doesn’t like happy accidents.
