Have the software turn it on when the wheel motor current (or command level) exceeds some forward value.

It's a bit more than this but not that difficult.
The major weight and effort is the safety cage. When you throw a prop it can do serious damage and may bounce off obstacles without loosing all that much. The trailing edge is sharp. IMHO only a complete shroud that prevents an exploding propeller from escaping will satisfy the Inspectors.
Props must also be balanced or the vibrations are likely to lead to failure.
