If you want a real "orientable brick in atmospheric reentry regime", check out how they steered the Apollo capsules back down. Kinda bonkers, but worked - they made it asymmetric and then rotated it depending on if they wanted to go down faster, slower, left, or right. Obviously it can't fly, and its glide ratio is actually brick-like unlike my facetious description of the shuttle. But it worked enough.

Kinda like a single control plane missile that spins (rolling airframe?), except... without the control plane lol.
