Run it with a new impeller. No impeller means no water for cooling. You have two water pumps; 1) a raw water pump and, 2) an engine circulating water pump. For now, the raw water pump is the one to get a new impeller in. Even if it looks good, replace it.

Water will not get in the oil through a degradated head gasket until it circulates through the engine cooling path.

Get it back to running and use it for a short while. Check the oil. The things you have said so far make me lean toward less damage. You may get lucky. White smoke is steam.

The smell is likely hose material.

One thing about it now, the engine is not seized. 160 deg. F is normal operating temperature (NOT).
