I can't answer that question, Cloverjo, but it depends on how much the job would appeal to anyone, never mind a woman. There are lots of rules to learn, lots of time stood out in the sun (if you're lucky!); county cricket umpires have a four day job don't they? And for test umpires, lots of international travel followed by a five day watch. There may well be a few women who officiate in local league cricket. Might be worth Googling
