I'm not really so sure that is a good idea. The Majora's Mask was a force so powerful and chaotic that it was locked away much like the Fused Shadows. In MM we see the the mask is both psychotic, vengeful and capable of destroying all of Termina. As far as I'm aware it rivals even the Triforce pieces and the mask wants everything to burn. Do we really want to give one of our everyday characters that much power.

You have a great point there, but it also is a prominent relic in LoZ history. Hmmm... We could switch it out for one of the more generic magic masks within [i]MM[/i], but I don't believe anyone but link could access their transformation power. Plus, almost all of them are possessed by the happy mask salesman, we may need to just assume HMS has kept Majora's Mask since the catastrophe in Termina.
