Air cooled fixture issue

i just recently started my first grow in a long while. The equipment used was bought on a tight budget.

I’m not too bothered by the fact that I may not get the greatest yield out of my cheap led light. I’m just getting my green thumbs back before going full throttle.

I have a 4” in-line fan. I believe in the 200 something CFM range. (At work don’t have it in front of me at the moment)
After this run I’m going to get an MH and HPS system with and air cooled fixture. Winter temps get low in the garage so the heat from those will be usable by the next run.
I can find fixtures with 6” openings.

My question is can I use a 6 to 4” adaptor on the fixture and keep using my 4” fan?
