I like the idea in principle, but I propose a modest modification: how about we appoint a *competent* man to the job?  I mean, swapping out the current minister with some of the incumbent men in other portfolios wouldn't exactly instill confidence. Although with a cabinet size approaching the capacity of an airliner, there are a few men who would probably do a fantastic job. 

That the ministry of women hasn't achieved much has a lot more to do with the calibre of the comrade than the gender.
