To be honest, until you actually measure the room response you have no idea what it actually needs. Not only a static snapshot in time but also which frequencies ring and for how long as they decay (IE: waterfall plot). Thus, you'll only be making it sound good to your ears which is going to screw the mix up for every set of speakers outside of that room.

Secondly, EQ can typically only smooth out the small remaining inconsistencies (after fixing the room) but it can do nothing for 95% of the issues created by the room itself. Until, you know what the actual response is and why, you are flying blind.

If a room has a 10 db dip at 300 cycles because there is an axial mode issue at that frequency because of the physical size of the room, then adding more energy with an equalizer at that frequency, will only add to the problem. If you keep pouring energy into a hole in the frequency response curve all you get is a deeper hole. One can apply the same rational to bumps in our room response curve. Bumps in our room’s frequency response occurs because frequencies bounce up and down upon themselves in phase as a direct result of the physical dimensions of our rooms.

Fun to mess around with though; I learned an awful lot by experimenting.
If it requires a null test to find it, it is by definition minuscule.
