It's worth a try, indeed.

I doubt this would work: I very often use M-u, or M-c repeatedly to
apply the change to a bunch of words: assuming the first word is
all-lowercase, what should your new command do on the second invocation:
apply the same change to the second word or cycle the capitalization
style on the first word?
