Yes, I can say for certain that it is possible to edit the required AP for each Ability in kernel.bin. If you want to try for yourself: The ability list starts at offset 0x40E4 in this order (see Ability values).I have a question: do you think it will be posible to edit the amount of AP for the GF's abilities ? For example giving 20 APs to learn for the Draw command.
