I agree with being stocked to your limit now. Also agree about rehoming the Tang. "Small now" does not mean it will not have/cause problems.
If you upgrade in size, I would consider getting rid of the damsels. If they are not already, they tend to become very aggressive and cause problems. Switching tanks is an ideal time to get rid of them. They are normally buggers to get out.
