How can I generate tileset borders that account for tiles being destroyed?

I am trying to generate borders around a tilemap to make the tiles appear a little less rough around the edges (pun not intended), very similar to how the game Spelunky does it. The below is a good breakdown of how it works in that game.

Spelunky Tile Generation
==============

The purpose of this program is the creation of graphical tiles based on segmenting a 2D boolean array into chunks.

I created this to try and emulate the style of the terrain generation in a game called Spelunky. After studying how their terrain worked I ended up with this. I may add more to this in the future.

An example of the game Spelunky, and the tiles I'm attempting to recreate, is below:

#How it works

Their tilesets look like this (an single area excerpt from a much larger atlas):

I've highlighted the chunks of 2x2, 2x1, 1x2, and 1x1.

I broke their generation down into two processes:

My question is, how would I go about achieving this in Godot? Are there any features in Godot which would make this a simpler process? Anything in Godot 4 that would help?
