Pfft... I know a lot of people that've tried that and got whooped by the wireframes.
The way my cousin did it was using Falco staying on one side of the level using his blaster to keep all of the wireframes away from him. If they somehow snuck up behind him he just repeatedly dodge rolled right to the other side of the level continuing using his blaster (this doesn't work with Fox since his blaster doesn't make enemies flinch). He didn't get attacked by the wireframes at all. If you use this method well you'll be able to unlock all of the Multi-Man Melee goodies!!
Of course, Cruel Melee is a whole different story...
