No, because the neck for an S7320 is 22 frets. All other 7-
string necks are 24 fret. I think though, Ibanez was going to (or already did) come out with a 24 fret S.......but not in the 7 string variety......Someone correct me if I'm wrong on this....Besides......a different 7-string neck wouldn't really be customizing it all that much would it? Unless you had one made by a luthier with say...a reverse headstock, different inlays...
