No for the reason that 3DS games would look horrific on a large TV display, they're already fairly grating these days on a 5-inch display I can't really imagine it going well on a 50-inch display.
If there was a way to run the games at 720p or 1080p then yes absolutely. Monster Hunter 3U on the Wii U looks great and that's basically just a 3DS game running at 1080p.
Next-gen when the handheld is capable of HD graphics or something in line with the Wii U -- that's a different story.
To be honest going back and even playing Super Mario Galaxy 2 again on the Wii U was a bit of a rude awakening ... SD really looks terrible on HDTV sets. Thank god the Wii era is over, HD is soooooo damn nice on Nintendo titles.
