You could, but no grille or headlight surrounds will fit, indicators won't align with guards. I've seen it done with a HJ-HZ single light support and a home-made grille but it looked like something from Mad-max. If you are able to weld well, go and find a damaged twin nose, cut the top half off and weld it to the bottom half of a single nose. I used to do this when I was in high school, so it isn't all that hard. You can do the joints basically under where the bar goes so it doesn't even have to be perfect. I used to buy every smashed twin nose I could find and make them up out of the good bits.
