what is and is not a bass trap ....

Tiny.

Sure, you can certainly help with modal issues with multiple subs and careful placment. Are you ever going to completely eliminate all axial modal issues in all 3 dimensions, not to mention the tangential and oblique modes simply with additional subs? No - not unless you plan to literally have dozens and dozens of subs in the room.

Also, one must do a feasibility and cost analysis. Would you rather spend $6k on 4 decent subs and lose a ton of floorspace placing them to deal with the axial modes in 2 of the 3 room axes (no help for vertical modes when they're all sitting on the floor...) - OR - 1 to 2 killer subs that will knock your socks off and treat the room accordingly (which will also deal with the tangentials and obliques - not to mention assisting with general decay time control)?

I'm thinkiing that the first mode or two in each direction is the most troublesome - and the hardest to damp out with corner traps. I wouldn't use 2 or 4 subs in lieu of bass trapping, just as a suspenders to compliment the belt.

Floyd Toole published some studies suggesting that you can do a lot of mode cancellation with just two subs. One "extra" sub isn't much to pay if the lowest 2-4 modes in the room are tamed.

The other thing I have going for me it that new construction here in Oregon is typically 2x6 studs on 24" centers - so I already have pretty effective panel traps.
