Is it possible to update Characters who were in Brawl/PM and are still in Smash 4 to have new audio?

As in using Smash 4's Pit's voice for PM Pit, and maybe even new sound effects.

Has this been considered at all for future versions of PM?

Then again, PM has said that they won't be adding any characters newly found in Smash 4...

Why would you want to replace Pit's voice!? How am I going to be able to goad people into attacking me when I can't use pits annoying voice?
"TEH FYITE IZ ON!"

I don't think they want to take any assets from Smash 4, including audio just to be safe.

But since Pit has the same voice actor in Kid Icarus Uprising, I don't see why they couldn't take some audio from there.

I doubt PMDT will do anything about it, but I'm sure someone else has.
