RE: Short story with pictures.

1. It still makes a difference if you leave more room to the front wall. The angled drivers in this close to the wall setup are a benefit.
2. Without the time or phase adjustment to get phase alignment the LR4 crossover can leave a big hole.
3. You don't need a complex XO for bass augmentation just a good phase adjustment and placement (time alignment) to match up with the -180 deg phase of the bass at the XO freq. so that there is no cancellation at the listening seat. A simple Rane 22 will have a delay/phase adjustment on the low pass section. You just need to get the phase difference to go -90 deg to +90 between bass and mains Instead of -180 to 0. If you want a smoother transition you can do a symmetrical 1st order and add the LR4 crossover about half to one whole octave above.
4. Not enough to get the most bass output out of them. The difference is substantial with rigid bracing.

6. Do a preliminary trial with rough placement to just see how it works out and whether it is acceptable space wise.
