If i remember rightly, steve's "signature" sound is usually in the Lydian mode so it may be an idea to throw some of that in there aswell Try get it put into guitarpro or even better recorded, id love to hear it!
lol, steve usually uses his theme to outline chords, not to mention he doesn't stay in any single mode for too long.

we can't make any suggestions without seeing a melody. if you want to see what chords your melody might outline, look at the notes on the strong beats and look for arpeggios and chord tones.

I've uploaded it now, it's called Instrumental. It's sloppy atm, and a work in progress too, I just got it down so you could help me. It is on my profile.

Try a F#/E --> Emaj7 vamp.
