Maybe you should suggest this "improvement" to Bobby Weed and see what he thinks. I admit the 11th hole is a tough tee shot, but not if you hit an accurate iron. You don't have to hit it very far to have a reasonable distance to the green. Like the tee shot, the approach shot needs to be very precise because it is a long and narrow green. I don't think there is anything wrong with the hole. It has unique demands and offers variety, something I know you value. I don't see why you don't appreciate the hole.
As for the 17th, I like a high demand penultimate hole and this one really works as a very short par 5. It has a high demand tee shot (no need to hit driver) and the approach to the green is very good with the fronting bunker creating some real interest as well as the severity of the green slopes.
I wouldn't change either. The course is very cool as is.
