So far,we've got a number of considerations to think about and there's no generic recipes for low drag mirrors.
Drag will be affected by:
*location
*distance from body
*shape of housing
*shape of mounting stalk
*frontal area
*local velocity
*local flow pattern
*degree of mirror inset from 'end' of housing

Here you can see the difference in drag for a solid body of revolution with a prolate elliptical nose.The lowest drag bodies are rather 'long.'
