Is it possible to create custom console commands?

[MF99K]

If so, how would I do this and is it possible to swap ground types (regular vs impassible) using custom commands?

You can do anything in the console. Just make sure your function is global, so if you're creating it in modmain.lua;

function GLOBAL.commandx()
	print("command-x")
end

Are you asking if you could swap land with water and vice versa? I've seen multiple mods do this;
