Hi - As the "Crooner Horn Guy" I can confirm that no Maj7#5 chords were recorded for this style.
In your case, For your Ebmaj7#5, I suggest you choose a G (major triad) for the horns as a workaround.
Good luck!

P.S. Looking at your thread more closely, since you're going from Ebmaj7 to Ebmaj7#5 try a Gm in place of the Ebmaj7 and Gmaj for the Ebmaj7#5 and that way you may find better voice leading in the horns. Just a thought.
