Am I just asking for (more) oil leaks with using a lower viscosity oil?
In which case all our cars would be leaking like crazy once hot... When cold, the oil is like maple syrup and at no pressure, while running it is almost as thin as water and under up to 7 atm of pressure. You should rather find the cause of the leak and eliminate it rather than trying to cure it with thicker (when cold) oil. 20W-50 is exactly the same viscosity as 5W-50 when warmed up, but the 5W-50 starts lubricating a lot quicker after starting up.
