The problem with changing the footpeg locations is that the relationship between the pegs and the shifter or brake pedal will be compromised. Without adjusting both the shifter and brake pedal they may never again work well together...and no-one, to my knowledge, makes a shifter/brake pedal relocation or adjuster kit for the CB1100.
As a taller rider, my solution was to go with a higher seat which made my long legs much more comfortable. Unfortunately, a custom Tall Corbin or K&H seat can be quite $pendy compared to some lower pegs
