I don't see an addon like that being a thing as it deviates the initial tech progression. Reika likes to keep his progression gates pretty tight. If these engines bypass any tiers he will likely not endorse it.
That being said the idea does sound interesting, frankly I sometimes find the strict linear progression of RoC tiresome after a while. There is very little in the way of alternate paths. I think so long as the alternatives are unable to supplant the ethanol/ jetfuel paradigm Reika MIGHT not attempt to counter the idea. But that is easier said then done, I suppose the finite nature of the oil will persuade players to set up jet fuel facilities. But by the sound of things your idea will most likely let folks jump teirs.
