Writing Fugues In Minor

I've been developing my own abilities in counterpoint for a while now, especially in Fugue writing. I've discovered that writing fugues in major keys is ridiculously easier than writing them in minor. I know why it is this way because of the more harmonically malleable nature of major keys and scales, but I'm trying to figure out how to get myself to point where writing fugues in minor is just as easy.

What are some of the melodic, and harmonic techniques that would ease the unearthly pain that is minor fugue writing?

Are you familiar with the melodic form of the minor scale? It has the natural 6th and 7th going up, just like the major scale. And the flat 7 and 6 going down, just like the natural minor scale, and the flat 3rd to keep it minor at all times.
