As others have said the prop, motor, ESC and the size and number of cells in the battery have to be considered together and each item has to be kept within their individual specifications. Significantly change one can lead to problems with the others.
If you want to turn a scale diameter 4 blade prop your first requirement will be a motor with a much lower kV. This will run a lower RPM for the same voltage and should draw something like the same as the amps as current. You will then find although it has the same total power the plane's performance will be lower as a 4 blade is less efficient than 2!
By the way the Spit Mk1 started out with a fixed pitch two blade prop, then 3, then 4, then 5 and finally 6 (two 3s contra rotating). Take your pick!
