You're not supposed to KILL people with it, you're supposed to INITIATE with it. That's why it's CURRENT HP - You chunk them down from full to make them weaker so your team (and you) start the fight with an advantage. If you're trying to finish kills with Evelynn's ult, you are playing her completely wrong.

NOTE: A typical late game Evelynn has around 600 AP. Your idea makes her ultimate weaker against anyone above 2300 HP - which is to say, everyone. This is League of Warmog's. The only thing keeping Evelynn remotely viable in the current meta is the fact that her ultimate is percentage health damage.
