The helix angle has to be increased to make it possible to backdrive but you also increase the torgue required by at least 20-1. Better to buy gear boxes with spur gears and have an engineering staff to help with the selection so as not to waste time and money. You can try cgi motion or others for cataloged Nema sizes and only have to buy one.
