Of course, easily. Switzerland has been using pumped water for storage almost a century. Here is one example:
It doesn’t use wind power exclusively for pumping but any surplus energy. In the past this usually had been French nuclear energy, in the future it will be mostly solar and some wind.
Could pumped hydro be combined for energy storage from offshore wind?

I don’t see why not, provided you have the geography to make it work.
