This you can already do; see Keymap preferences: https://www.haiku-os.org/docs/userguide/en/preferences/keyma... -- you should be able to just drag & drop the keys around to swap them. Or you can edit the keymap file directly to completely customize it.

We have a ticket somewhere to revamp the hardcoded shortcuts into the "Shortcuts" preferences pane; but nobody's done this yet. Eventually...
