Even if it's technically grammatical, I don't think it's something a native speaker would generally write or say.

"You need X?" works in a casual setting. But IMHO it looks pretty out of place in a more formal sentence like this with so many fancy nouns.

It could definitely be reworded to be at least easier to follow. I guess this is where Spanish is useful with the inverted question mark. ¿
