I assume this would require some advanced soldering, but would be possible to replace the SSD with a larger capacity SSD if one was willing to radically violate the warranty and solder one onto the motherboard?

Sadly no, the density (chips on both sides and very close to one another) on the logic board makes it impossible to desolder these chips without damaging things. It would be cheaper and easier to just swap out the logic board (if you have the 256 GB model).
You also won't be able to find anything larger than 512 GB presently that fits the chips location; Orange block Toshiba TH58TFT0DFKLAVF 128 GB MLC NAND Flash shown 128 or 256 GB one on each side for a total of 256 or 512 GB.
In the next year or two you'll likely see larger density chips but again its just easier to swap out the logic board.

It's not a problem density wise, phone repair technicians do this all the time. The flash memory solder pads are large enough.
The problem is that the chips are on both sides so reheating the board at least 4 times (2 times remove the chips and 2 times to solder the new ones, if you aren't quick enough) will very likely to ruin it.
Also, since they are bare flash memory chips, not complete SSD units, you will likely need to do some low-level programming for the system to recognize the new chips.

If it is just soldering, it can be done. However the flash memory chips are not like standalone SSD modules, since these chips are designed to be completely embedded to this board, there may be special low-level programming to be done with the new chips.
So I say this is unlikely to be viable.

It might work, but you might have some problems. I've never tried that before with any sort of flash storage, but your welcome to.

you have got to be kidding.
If you do it correctly, it MIGHT work.
What are going to put in it, where are even going to get it. This is no hack job.
I said that I've never tried that before, but I can't think of a reason why it wouldn't work if you do it correctly.
What about from digikey?

Thanks for all the feedback. Seems like a low-probability proposition right now, and even if there is a replacement option (I'm looking for 1TB) then it still might be a high-risk job. Sigh...

Sorry, nothing at that high a density available on the market quite yet.
Here's the largest flash just intro'ed just a few months ago: Samsung Mass Producing Industry’s First 512-Gigabyte NVMe SSD in a Single BGA. Two of these would get you 1 TB. I'm sure Apple will offer this size in the fall line up (both Mac's & iPhone's).
Again, you'll want to swap out the logic board here when Apple offers a replacement bd.
