I have never seen the geometry of the 281 steering. if its anything like the 323, it might be fairly easy. The 323 emergency tiller fits in a socket atop the rudder post. That said, an extension post could be fabricated and installed to which a tiller could be fitted with the use of a clamping ring.
Pedestal removal and steering quadrant should be fairly easy to remove, especially if there is a removable section of cockpit floorboard.
I suppose its a matter of personal preference, but why would you want to go back to a tiller? That would seem to require more real estate in the cockpit for swing room.
