There are multiple reasons for signs to have different shapes, sizes, and colors, and this is one of them.
An orange diamond "detour" sign isn't easily confused for a smaller rectangle "one way" sign.
Additionally, there should always be two large "do not enter" plus two large red "wrong way" signs that are visible to a driver from in the intersection before turning.
Something as simple as tape or other coverings on an existing sign should never result in any confusion as to right-of-way for a driver paying attention.

Some people key off the shape enough that they wouldn't follow a wrongly-shaped detour sign, so you wouldn't fool everyone, but you'd absolutely fool a lot of people. I expect I'd be one of them.
