I am against actually changing the invocations as printed in the rulebook, mostly because I hated the way Wounding looked in 6.0.
I would instead simply put a note in the actual Healer section of the rulebook stating that such single-word substitutions are allowable for the sake of roleplay as long as it is impossible to mistake the nature of the spell being cast.
Actually, I'd make that an option for all classes, but I'm a flurb like that.
