You want Yuu to look like persona 3 main.. cause you wish he was there? Yeah we can do that.
If you look close at this one you can find a 'yukari' one. You might not get her or the p3 main, but they will be there in spirit. Some of them I don't know about or need an image to compare but I thought it was a neat concept as a whole. Check out Siliconera post for more of the pallet swaps and in the comments, there is even a Teddie one like Tao from blazblue.
Unno.. something neat.
