Will blowing hot air into a return air duct reduce the amount of gas used to heat?

Depends on where you get the hot air from. Returning hot air means the furnace will have to work less to heat that air back inåt output temperature. OTOH the energy to create that hot air has to come from somewhere. Using a space heater or something to blow into the return ducts will cost you more in electricity than what you save on the furnace .
