Hair as an olfactory organ: Feasible or dumb?

Within my setting, insects, due to a rather long (millions of years) and convoluted (gods suffering from empty nest syndrome) series of events, have evolved their exoskeletons into an endoskeleton of sorts. During this transformation, which is explained in this question, many organs and sensory organs changed and were modified. One such organ was the antennae, which moved to the back of the head and multiplied until, to a human, they look like hair.

The question is simple, does this make any sense?

How well would it function as a smelling organ?

Is there another structure that the antenna can modify into that could smell better?
