Yeah, that would be good.

The kind of thing I'm thinking of is a sign we have in at least one private parking lot that has the exact red octagon with white edge but instead of STOP it says SLOW DOWN. It is literally a STOP sign that says something else. That has text, but isn't a caption and only works because the context + words causes a double take.

I'd be ok without something like that and going full image only if that seems like a hard nuance to moderate.
