How about we make Pokemon Trainer, Toad, Chrom, and Takamaru's graves "Platinum", and give golden graves more liberally; or start giving out silver and bronze graves as well.
I'm more or less OK with this, except for I think platinum graves should be reserved for any vets in Brawl that were in Melee such as Ice Climbers or Falco (to keep the higher-ranked graves for characters that already were playable), and then if, Arceus/Rosalina/Hylia/Captain Falcon forbid, Ness or Jigglypuff get deconfirmed, being 64 vets, possibly something else on an even higher magnitude for their potential graves (Stardust? Cosmic Energy like Mario Galaxy?).
Basically, my hierarchy would look like this:
Stone Grave: The not-so-highly requested characters (Starfy, Balloon Fighter)
Gold Grave: Brawl Newcomers (Pokemon Trainer, Snake), Melee-only characters (Mewtwo, Dr. Mario) and highly requested and practical shoo-ins (Chrom, Takamaru)
Platinum Grave: 2-game vets AKA Melee vets that were in Brawl (Ice Climbers, Mr. Game & Watch, Falco)
Stardust Grave: Probably unnecessary, but just in case; Our last two 64 vets, Jigglypuff and Ness
