2x Top Fans as Exhaust Useless?

I have a storm scout 2 case with 4x intake (2x front, 1x hdd, 1x bottom), and 3x exhaust (2x top, 1x rear). I also have a vertically positioned 212x with 2 fans in push-pull.

In spite of having more intake (positive air pressure), I feel like my system is having more of a negative air pressure. I say so, because the 3 exhaust fans have no obstacle, as opposed to my 2 front intake fans which is obstructed by the HDD cage, and the bottom fan intakes the least amount of air. Of the 4 intake fans, only the HDD fan brings in the most air.

I'm thinking of making the two top fans as intake. Is that ok? If I do that, only the rear fan wil act as an exhaust. What can I expect (both good and bad) from having that setup?

Hot air rises, cold air descends; fighting this trend can lead to weirdness and generally sub-optimal airflow.

But, you know, no harm comes from trying it out. Have fun, for science!

Alternative, you could try taking out some exhaust fans; effect a situation of true positive airflow, and see if it actually is beneficial to your situation.

Yes, I think that's worth trying. When I'm gaming, the 2x top exhaust fans really help in dissipating internal heat (I feel the warm air going out.) What concerns me the most is when I'm not gaming. Since my rear and 2x top exhaust fans are plugged in directly to the PSU, I have no means of switching it off and it runs at max speed all the time.
