Re: Offsetting shifter piston?

Heck, I can't even fit a thin long piston there.
I'm faced with two options: Place the shifting piston behind the cims (~4.5" away from the shifting shaft) or to put the piston to one side and connect it by a bar to the shifting shaft. Is it dangerous to offset the piston to one side and use a metal bar to connect the piston to the shifting shaft?
How much offset would be needed?

Or even better, a CAD drawing.
