It depends on what rules you are allowed. If you are allowed Conditional Proof you don't even need the premises:
P3) K (ACP)
P4) K>K (P3 CP) QED.
If you have a more limited scope of rules that you can use, it gets harder, but in any case you don't need the premises. If you have the LEM and the definition of Implication, you can also do it pretty easily:
P3) ~KvK (LEM)
P4) K>K (Impl)
The point is that the premises are unnecessary to imply the conclusion. The conclusion is simply a necessary truth of classical logic.
