catch can vs. overflow bottle?

Real quick..

Can the coolant overflow bottle be substituted as a radiator catch can for drag racing?

i ditched the stock overflow and bought a moroso overflow for like $23 from summit. it holds a quart, its black, plastic, has a drain on the bottom, and isn't an eyesore like the stocker.
