An exceptionally poor idea.
Aside from losing all save data, titles and so on, you're also tampering with your NAND, which you shouldn't do.
The only conceivable reason to have this is for piracy, and the only way you can do this is if you already run arm9loaderhax or boot9strap, meaning you can do this already using much more convenient tools, which makes doing this a pointless endeavor.
Just don't fucking do this.
