You might be in luck... but I have no idea why you would want one other than to scrap parts/cases or do a hardmod. But that would require you have a NAND backup of the bricked system.
i plan to swap out my PCB becuase my 3DS took a fall it boots but both screens are shot as well as the hindge. I can barely see the games and i can hear the music.
I have a friend who has a black screened bricked O3DSXL, but for the shipping itself you might be better off going on eBay and buying replacement parts and a new casing. There are repair kits... google it.
