From what I understand and what I've read, it would take less than 200 lines of code to make at least a simple version of this implementable into the game. While I know absolutely nothing about API and very little about coding in general, I would absolutely love to be able to put the finishing touches on a creepy or ominous atmosphere with torch on the opposite wall barely throwing light to the edges of a corridor or cave, only to have it flash brighter, and die down again. But, seeing as I don't even know where to open the API script doohickamajigger, I guess I can't judge how hard it would be, though I would love to commission someone to make it possible and easy-ish to use.
