Never going to happen. The core code-base changes between .5 and .9(and this goes for any engine really, later than 4.7) alone are too great to be futzing around with an already working engine and a game that is used by hundreds of thousands of people. They have an entirely custom engine and they pull features they want or changes/fixes they need from newer engines, no need to deviate.
This is already a thing? Either directly or workable, I’m pretty sure there’s two means of determining this.
Also not going to happen. The core of ARK is done entirely in C++… you can’t just turn C++ into graphs either literally or ethically due to the inherent performance/optimisation gains from working largely in native code and some things just can’t be done in Blueprint. The best you’re going to get is when they decide to do new mechanics/features in blueprint, which they started doing a couple of months back.
