Easy/Possible to globally change prompt strings of messages? e.g. changing find-file's prompt string from "Find file:" to "open file:" ?

[Chris Seberino]

Is it easy/possible to change the prompt strings of various Emacs commands?

For example, what Emacs calls find-file I think of as "opening a file"
and hence would like to change the prompt from "Find file:" to "open file:".

Are global changes like that possible/easy?  Perhaps it would require
an Lisp style macro or something?

Thanks!
