There are basically two options I can see. Move the fan out of the tent, and put the filter right up against the wall, or move both the fan and filter out of the tent. You may need to be able to move the light to 3" from the top of the tent.
I have a 5' tall tent, and the plants grew above the light during every grow. I bought a 7-8' high 2' X 4' Gorilla clone to give me more height. Perhaps I went overboard, but I also built a tent topper to pull the air from the top of the tent. I now have 5' of space for the plants to grow above ground level.
