Would the opposite wall covered in subs, wired out of phase with a time delay work, so they would "such" the pressure wave from the sub wall, giving the effect of a wall of subs in an infinity long room?
Right.... this is new t me. And do you need as many "out of phase subs" or less can do the trick?
It makes sense to have an array which is effective by the same standards as needed for the front array. Basically even distribution and enough subs to be close enough to handle up to your highest needed frequency.
Active bass traps should be able to do the same thing and also be able to compensate for discrepancies.

If I had the right space for this, I would be trying this out!

I don't quite understand what you mean by bass sound moving from front to rear?
With a front array of subs (plus some rear trapping) I don't see how omnidirectional bass
including 'normal center panned' bass can move from front to rear?
The array works as intended when the bass is mono and the panning can be left to higher frequencies.
The waves only travel away from the array, not laterally, since this is where the pressure gradients apply. I suspect I may need more information to understand your question properly.
Yes, you're talking bass below the modal region where location is not relevant and arrays are unnecessary.
Yes at frequencies where the room is modal. The wave will travel as a plane from the array. Consider this simulation..
Sound primarily does not travel from left to right.

What would be the reason, if any to increase from 4 to 8 sub locations on the front wall?
The increase in high frequency does not really count as a benefit for subwoofers the way I see it. One would not want to play them above 100 Hz anyway.
