No, the Scruffy is too short, it can't do the little tails on the sides. It could be done with extensions sewn into the sides but not otherwise.
I'm personally using a Wisp in 24b for my Toon Link cosplay (not a color I reccomend if you're doing his Brawl version actually, it's too yellow, go with 24 if you get a Wisp). It works okay but the back's a bit long and the sides are a bit more layered than I'd like.
If you want to cut as little as you can anything with a short back and longish sides could work. Off the top of my head:
Bangs a bit short
Any of Amphigory and Cosworx's short without bangs styles with a layered back, you'll just have to cut bangs
If you're not afraid of doing more cutting than that, just about any base wig longer than the chin will work, since his hair doesn't need extreme styling to accomplish. Just a short, layered back, long side thingies, and longish bangs that you can mess up a bit with pomade or hairspray.
If you want the color as accurate to his Brawl version as possible, I'd skip the ebay wigs, because you never know what shade of blonde exactly you're going to get in a blonde wig. If you like I can go through my color ring for you later. :3
