I just read a bit about that recently and will be looking to tackle something similar if I revert to tiller. I don't think my re-conversion would be as involved as yours was as the tiller, which we still have, would attach as usual to the rudder post in the cockpit as usual. I think I'd just need to disconnect the cables, remove the binnacle/wheel assy, and find a way to cap the deck reliably. Ignorance is bliss... Could it be that straightforward?
