Possible, maybe.
Practical.....definitely not.
When on the highway, it's not necessary to keep your instep planted on the pegs.
Try hooking your heels on the passenger pegs.
Put your ankles on top of the pegs and feet out front.
For a real unique experience, shift your butt back to the passenger seat.
Most importantly, move around.
Regardless of what riding position you have it won't be comfortable to STAY in any one position for hours on end.
