Nothing can stay hidden behind the Sun, because we keep moving around it.

Would such an object still be seen so easily?

A huge dust cloud would make it even easier to see. It would reflect light from the Sun, glow in the infrared, and obscure stars behind it.
Just to add to that, a brown dwarf, in a dust cloud or not, that close to us, would be a very bright object in the infrared. Any of the large IR telescopes would have seen it long ago.
