It's possible, and would be very fact dependent. At common law (and as a result in many jurisdictions as they engage in their butchering of the MPC) there is often an independent doctrine of imperfect self defense. Self defense is a complete defense, a super justified excuse (see what I did there) for killing another human being. But if the claim fails while still objectively implicating less guilt on the part of the actor, the jurisdiction will likely seek lesser charges and/or make an imperfect self defense claim available.
At common law, the malice requirement (while usually not really meaning anything) might gum up any conviction for murder if there was a shaky self defense claim.
