Earlier in the war the decision not to kill Hitler hadn't yet been made, that seems to be a decision after it was pretty clear that Germany would not win in the East and would be doomed anyway, about the time of the unconditional surrender line, so what if the Allies had gotten lucky and managed to assassinate Hitler? Let's say its clear that it was an Allied plot too, say they get good intelligence and someone willing to do a suicide mission to get him. What then? Let's say its some time in late summer or autumn. Can the regular military scramble and stop Goering or would Goering be able to grab power on Hitler's succession order from 1939? Would the Allies potentially be more open to negotiations? Would they be more open to encouraging the resistance to topple a Goering government?
