OPA552 as power regulator

Of course it will work, and we'll sell lots of them. I've done many similar circuits, and all of them have worked.

The OPA547 is a better opamp for this, with its programmable current limit. We'll use that one. Thanks, Lasse.

make anything work.

That's even easier to deal with, you end up with near 90o phase margin, mor e current drive, and direct current limiting:
