[pokeemerald-expansion] Is it possible to create an ability to change a move from Physical to Special(and vice versa)?

[Houndoom10ftw]

I have been toying around with an idea for two abilities and want to know if they're possible.

1. An ability that makes Punching moves Special. (Not targeting Special Defense, but using Special Attack for damage calc.) (I don't mind if they target either defense or special defense)

2. An ability to make Sound moves Physical. (Not targeting Physical Defense, but using Physical Attack for damage calc.) (I don't mind if they target either defense or special defense)

My questions are:
1. Are they possible in the first place?
2. For the Sound ability, what would happen with the Status sound moves?

1. Neither of those abilities do anything that the Game Boy Advance is not capable of. Therefore they're possible to implement.
2. That entirely depends on how you decide to implement the ability. Seems like keeping them as status moves would make the most sense.

As a hint for how you might implement those abilities, the expansion's damage calc has a variable called swapDamageCategory, which swaps the move's category if set to TRUE. You could add some code to set its value based on the ability and used move, but note that without further checks that would make status moves physical.
