I feel for you poor folks who have such large places in the dark.
Maybe the best thing for you to do is get one of those tiny houses and leave the lights on...
The only time my place is dark is when the power is off (a rare thing) because my wife gets peeved at having to find her way to the bathroom in the dark.
Just checked, the longest straight line distance in my house is about 16 steps. Regular steps, not strides or yards. Plus its full of several decades of what most people would consider junk. I can watch one of the "hoarder" shows and think, …"what pikers!"
SO, clearly my situation is quite different from yours. I find a "standard" length coach gun to be just fine, though more cumbersome than a handgun. If you want to play around with a short barrel shotgun, just accept the Federal limits and live with them.
A SxS eliminates 3+ inches of action length. You would need to build that lost length back into the gun to reach that magic 26” mark. Adding 4 inches to a 14” barrel takes you back into normal length (18”) barrels and any benefit is lost
I don't see how you figure that. The gun is still just as short, the only change is longer barrels to compensate for the shorter action length. TOTAL overall length is unchanged, so you don't lose what ever perceived benefit you get from the short overall length. Of course, by going to a SxS over a pump you do lose that 3rd, 4th, and possibly 5th round capacity, but, that's just the nature of the beast.
