Herd bound horse in box stall?

My horse currently lives in a pipe stall. But with El Nino coming around the corner in CA, I think I should transfer her to a box stall. The only problem though is that she is her bound. She likes to see and interact with other horses. Please any advice. If a stall is not the best idea what would work well to keep hooves dry and not getting thrush all the time?

Thanks!
