Modifying Differential Breathers????

Is there any way to modify them so that they dont get all clogged up from mud?? Im constantly on construction sites full of mud and I just had my transmission serviced and when they checked the rear diff, it was under alot of pressure because the breather was all clogged up from the mud.

Couple of links (I think you can just extend them):
