I missed that part about coming from A major so my earlier spelling would be an uncommon way of naming that chord. Chris you would definitely be right then by going to E next. Being an E augmented that's sort of weird, think that's a hungarian movement (I-V+). Could be wrong but I believe it is. You could call it an Emaj(b13), that would be right but I don't see anything wrong with calling it an E+, but you would have to note B in the bass (E+/B). The E+ triad exists in the a triad on the D, G, and B strings (X-211X = E+). Then you have B in the bass (X2211X). Of course there's no write or wrong since everyone names them differently.
If you happen to be going to A major next, it would be called G#+/B. Better voiced as G#7#5/B. Could be the enharmonic Ab depending on key also. Many many ways to spelling chords.
