Aldo vs. Edgar isn't a "super fight," much less is it a "mega fight" and neither would Aldo vs. Bendo.
The term super fight gets thrown around to loosely around here.
The only real super fights in MMA are GSP vs. Anderson and Anderson vs. Jones. Not even Jones vs. Cain would be a super fight yet. Cain isn't popular enough for that fight to be considered a super fight yet.
If Aldo beats Edgar(which can also be considered a mega fight) convincingly should he go up to face Benson and maybe become the first ever UFC champion to simultaneously hold 2 titles?
