Full 16:9 Widescreen Hack for top screen

Hello. I was wondering if one day you can maybe implement a full 16:9 widescreen hack where you can see more of the top screen without stretching the image.
The 3DS top screen has a 400x240 sized screen, but when displaying it on full screen on a monitor, there’s some small black bars on the screen. A full widescreen screen would be like 426x240, just 26 pixels more than usual to remove those black bars.
Of course this is just an idea I had for a while, and you don’t really have to do it, but it would be really nice.

Thank you.
