Well...jokiness is nice, but someone like Donald Trump is very used to receiving business ideas - many of them. People at his level are like Hollywood moguls: they treat would-be opportunity providers like moguls treat wannabe actors, directors, etc.
Given Trump's business record, if he gets interested at all he'll be interested in a fork. Trump Steaks, Trump Water, Trump Coin.
Is still think a coordinated would generate interest at least to a demographic that would be interested in a decentralized communication platform.
That's a good point. You're right: if Kanye West had sued to take over "Coinye" rather than take it down, and had run it in the way he liked, that would have been incredible for Bitcoin & the others.
Same thing if (say) Katy Perry had discovered Dogecoin & became a shibe.
