Richard,
You always just unbolt the column from the body, let it drop a bit, pull the blinker housing and cut away the key plinth. Fill the hole in the side of the housing, sand, and paint like I did with this one:

I drilled a few holes around it for more of a "race ready" look, but you could keep yours smooth and "stock" looking. This way you can get a nice "look" and also keep your blinker, steering wheel, and directional wiring intact. Move the ignition wiring out the housing and to the dash. Drill a hole in the dash for the key switch surround to poke through, fashion a small bracket and you can even use your original key switch.
Maybe?
