I'm not sure you can. There are two routes from T5 domestic arrivals to T2 departures. Landside via rail/tube or airside. Landside involves a boarding card check at T2; airside involves a boarding pass check at T5 along the way to the flight connection centre. At both control points you'll need a valid boarding pass for an onward flight to proceed
