I've done the same modifications to my GT to get to the riding position / wind protection that I liked on my R1200RT. A Russell seat is next, and if that does not do it for me I am thinking about another RT or quite possibly a Triumph Tiger.
As for your hand going numb, I tend to have the same problem. High frequency vibrations do it to me, and not course vibration like you tend to get on your old boxer.
Here's a side by side comparison of the ergos. Note that even with my SM bar risers raised all the way, my arms are still noteably lower than on the stock RT. Also, my knees are bent significantly more even with the SM pegs.
