Its your choice, but it would be sacrificing performance for aesthetics...
Check out the skimmer box add-on for the remora (also on eBay), that hides the pump and makes it skim better, and looks better.
Back to your original question I think you only need to change the wooden Airstones once every few months but I have never owned one so can't be sure.
