I would not, but I never considered doing so.
If an Anemone has pest such as flatworms, for example, then I would not introduce that animal to my tank anyway. I noticed no endorsement or warning regarding dipping Anemones.
Basically I do not think the benefits of such a dip would be worth it. Hopefully someone that has actually done it will chime in.
