Yes, that's what I'd do. Humidity is part of a snake's natural thermoregulation- as long as they have the options they need, you're good.
I think this thread is extremely helpful too- now that I think about it, I wonder how many keepers are frustrated with trying to get the humidity up when it already is, at least on the cool side. And all that desperate "misting" they're doing may actually be detrimental- especially with snakes needing warmer temperatures, since warmth + moisture makes way too many bacteria very "happy"- (ie. might be promoting health issues?).
