In my youth I did about 500hrs on DC3s in Europe and can't recall this procedure of lowering the gear. Thirty seven years on my first thoughts would be fine if you have increasing IAS but what if you have rapid reducing IAS, with the gear down you have less excess power to overcome the IAS loss. The DC3s I flew did not have much excess power.
This is all assuming you can read the instruments which is almost impossible in "severe" turbulance.
