Creating a game using HPL2

[Measuring]

But wouldn't it be possible to create something in the style of a full conversion with it's own .exe and everything like Amnesia, But just replacing the entities, static objects and so on. And if you were to make a Horror FPS like that, it would be possible to create some tool for defense right? Just a lot of scripting.

Ofc its possible but it wont be too easy unless you have the source code for the engine. But making a new amnesia with only your content is possible.
