I would, did that with my '92 stang, it had a 6" hole for the foglight, but the fog light hole is too small on the crossfire. To get any sort of positive pressure to build, you need to start with a larger than 3" (manifold size) and taper down, to get an good increase in pressure (Bernoulli principle).
But if you find a frontal cross section area larger than 3" then you are in business.
