Notice anything? Yeah, Billy Batson is getting his powers DIRECTLY from the gods(plus Solomon) themselves. I think I'd be MORE okay with the name change from Captain Marvel to Shazam, possibly even like it, if they DID just cut out the wizard and have it be like this where he's getting his powers DIRECTLY from the gods. At least that way him being called Shazam makes more sense instead of it just being the "Shazam spell" where the name no longer is an acronym for the source of his powers and just a word with no real meaning. I mean it's an interesting take, but I think it works AGAINST the name change.
