You need to think through your theology here a bit.
First, you just said, again, that the standard for formal equivalence is italics but then scream that isn't what you say when I challenge you on it.
Second, regarding James 2:5, do you really think someone is rich in faith before salvation? The answer to that is no. There is none that love God before salvation (Romans 3).
Furthermore, let's look at the Greek. The word for "rich" πλούσιος literally means "to being plentifully supplied with." So you can literally say, "has God not chosen those poor in the world to be plentifully supplied with faith"
So no, it is not changing any meaning to add the words "to be." If anything, it makes the meaning MORE CLEAR and accurate. It is MORE literal than the translations you supplied as a reference. But again, Romans 3 makes clear that there are none that seek after God. So how can they already be rich in faith? That makes no sense biblically and it also makes no sense grammatically.
