Actually, you shouldn't have much trouble selling the wheel apparatus.... Converting from a tiller to a wheel steered vessel is unusually expensive and there are many uniformed sailors who think it makes their boat look more expensive, or is easier to control... both wrong assumptions. Big boats need wheels because the larger mechanical advantage needed takes up too much space with a tiller. Any boat under 30 feet though, a wheel is not really necessary.
Space wise... remember that the tiller lifts up, out of the way for a clear cockpit, and with an extension you can sit out on the rail and see the telltales while steering, and you're adding ballast also.
If you plan to sell the boat in the near future, re installing the wheel system will allow for a higher asking price.... don't ask me why... it's a desirable feature for beginner, inexperienced sailboat shoppers .....
