it might be possible to shroten the steering column with a bit of engineering, but not sure in the cost involved. or the time it would take.
probably looking at a complete dash strip (not so bad in an elise, as there isn't much dash) dismantle the froot and the steering system, cut down the column and then rebuild.
I'd need to move it upwards as when I squeeze in to the car my legs rest on the steering wheel so I can't turn it! I guess I could get a smaller after market wheel though.
