I doubt it.
I think they're reasoning for taking down the Super Mario 64 HD thing is because it partially replicated one of their existing products.
I know that Nintendo is fully aware of Project M, and the reason they haven't stop that is probably because it's an "original" mod, as opposed to say, an HD version of Brawl, 1:1.
Since Mother 4 is an "original" thing, I don't think Nintendo will pull the plug on this, but I could be wrong.
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
