I have about 350 hours flying a VG equiped C340. I think it is the best combination of speed, wx capability, comfort, and economy in its class.... for operations from one IFR airport to another with a max of 4 people. "But" and sorry to be blunt, I think anybody who operates this airplane into a 1600 foot strip needs his head examined.
Yes it can be done but there would be absolutely no margin on either takeoff or landing.
Our SOP was a 3000 foot field as a min and every take off was 0 flap with a 100 knots rotation speed(blueline on a VG machine) with selecton of the gear to up as the decision point (i.e. with gear down both throttles must be closed and you take your lumps straight ahead, with gear coming up takeoff is continued and engine failure handled as an in flight emerg)
Bottom line buy an Islander if you want to go into the really short strips.
