The way that comes to mind is to capitalize the phrase and then go back,
with `case-fold-search' set to nil, and downcase the words you want
downcased by `replace-regexp':

M-x replace-regexp \b\(O[nN]\|O[fF]\|...\)\b RET \,(downcase \1) RET

If you do this enough, it seems like a good candidate for a keyboard macro.
