(in a traditional context Descending MM is a Harmonic minor)

Josh,
The melodic and harmonic minor 'Ebmaj7#5' is actually a Augmented chord in triad position. It's not a major chord, the "#5" tells you it's augmented. It is correct as "maj7#5" with the "7" extension. Also, a descending melodic minor is a natural minor scale, not the harmonic minor scale.
