I.e turn some ability into a kd or something like that?
Also if talking about shifting abilites around, don't wanna live foreva from 33 to 15

It depends on what the ability wants to do.
I can make the server do almost anything; it's what the client expects the ability to do that matters.
To use the example of a KD - each KD ability has a certain ID which is sent to make a buff appear on the client. There's an effect linked to that ID that you must send in order to make the player appear as knocked down, and a certain value that must be sent in the buff packet to grey out the bars. Both of these are hardcoded within the client for the ID in question - you must send the right ID for knockdowns.
Hence, while most of the KD abilities have their own buff, there also exist generic buffs (called "Knockdown" or "Knockdown Mob") which have the same effect and which could be added to existing abilities to make them knock down.
Stuff like (to use an example) making Phantom's Blade into a Wounds buff rather than a shield is more problematic. The server will handle it properly, of course, but because the tooltip text and effect for the Phantom's Blade Defensive buff are hardcoded (showing the damage absorb text and the white "ring" which is used for absorption), changing P'B is not viable unless the buff and effect from a different ability with the desired effect are used instead, which creates consistency issues.
