No thank you. I think you at least wait longer than that. Acuna can play a corner OF spot, you don't have to trade him just because Acuna is a CF. If Acuna is ready and Inciarte is still giving you ~4 WAR, you'd have to get a significant corner OF in return for it to be worth it, and I doubt you could.
Just keep them both and prosper.
There will be a season within the next 2-3 years when Ender's defense starts to decline (dWAR under 1) and he ticks up with the bat to a ~.775 OPS. He will still post his normal 3-4 WAR overall, and the narrative will be "he is finally figuring it out offensively".
That is when I would trade him.
