That will be left to others who will use this as a base hack.
BTW, Mime isn't really usable as is because it can't be equipped properly.
All preloaded equipment is deleted from your inventory at the end of a battle and no more can be given in the menu.
It is possible to 'fix' Mimes, but would require some hefty ASM hacking.
This includes re-pointing RAM addresses so that Mimes can use either the Dancer or Bard's RAM addresses.
And then the Dancer or Bard would have to be re-pointed to use the other's addresses.
The point being that it would be difficult and time consuming.
