If it's such a big issue on your boat why not use a spinnaker sock instead? No rule broken, makes the drop easier.
Um, weight aloft, windage when reaching, disturbed airflow at the head of the kite, slower hoists and takedowns, snarls in the mechanism, bulk when stored below . . .
Err, have you ever used a sock? Not a snuffer, a sock.
Zip the kite into the full-length sock, tie the retrieving line onto something on the foredeck, hoist, pull on the sheet, breaking out the kite and popping open the zip from bottom to top, retrieve sock. Common practice on IOR maxis in the 80s. No reason it shouldn't work just as well today.
