The only problem with the "this is the way it's always been done"
approach is we end up with weather reports etc that are more suitable
for WW2 then 2012. If we're already mixing metric and imperial units,
what's the harm in putting a metric equivalent as well?


Cos all the aviation charts have ground elevations in feet. You really don't want any confusion here or even the possibility of confusion. It isn't much of a problem for VFR but IFR is a different matter. There's a giant international system where most of the world's aviation and certainly at the top end is done in feet for altitude and nautical miles for distance. Horizontal distances in meters is really bad news IMO. Changing to kilos or litres of fuel from pounds or gallons caused at least one major aircraft accident. Changing units is expensive and fraught with possibilities for error. Yes, its an official stuff up.
