would Bush be better used as a WR like Steve Smith

I think that a lot of people are overlooking the fact that the coaches use reggie to effect the defenses front seven. If you take him away from a backfield role, he will be playing a completely different game vs a defenses back four. Sounds nice. But it is a huge transition, and it will open Brees up as a huge target. The o line hasn't been keeping Brees clean on thier own merit.

Also, in the passing game, the offense creates mismatches for reggie by motioning him into a WR from the backfield. This happens when you force a defense to change from a traditional run defense to a spread 3 wide. That wont happen anymore after reggie changes position. I do think the team is using reggie as well as they can, and I think that is why you see so many receivers gettin so open. Brees isn't getting a lot of pressure, and you see guys like Stecker wide open 30 yards down field. Changing what the team does would effect all of that.
