4000 watt set up questions !!

Hi everyone this is my first time posting on here so not exactly sure if im doing this right, Im in the process of upgrading and building a new room gonna be a basement grow roughly 10x12x6.5 trying to figure out what is the best ventilation set up ? going for an open air room not sealed but i can be swayed to change my mind if its a good set up, the rough layout I have right now is 4 lights 1k a piece air cooled 6in hoods, gonna run the lights side by side in sets of 2 instead of 4 daisy chained in a row (unless that's a better idea) planned on having a 6in fan per each 2 lights, to pull air from the outside of the room through the lights back out the other side. For the room intake I was going to do an 8in fan and filter pulling from the basement air outside the room then intaking it into the room on one end and an 8in exhaust fan and filter mounted high on the opposite end of the room for exhaust and smell, also going to run a floor a/c unit inside the room with exhaust vented out of room and dehumidifier if its needed, should I have another filter and fan scrubbing inside the room by itself also ? anyone have any better ideas ? does this sound ok ? is it overkill with fans is it not enough ? ive been growing for years now just outdoor and 2k indoor grows thanks alot I appreciate any help
