This is a poor question, in my opinion, because it is open ended and ambiguous. What do you mean something other than unconditional surrender? And what time period are you talking about? And there is always a chance of something happening, so it's hard to answer, "Was there any chance?" type questions. Also, this sub focuses on what did happen, not what could of or might have happened.
A better question might have been, "Did the US and Britain ever seek a separate peace from Germany, allowing them to continue their war in the East?" Or, "Did Germany ever reach out to the US or Britain in an attempt to make peace on the Western front while still continuing their war in the East?"
In any event, to address your question... in January 1943, Churchill and Roosevelt met in Casablanca to discuss the next phase of the war and it was there that they made the Casablanca Declaration, in which they states the Allies would only accept unconditional surrender.
On the final day of the Conference, President Roosevelt announced that he and Churchill had decided that the only way to ensure postwar peace was to adopt a policy of unconditional surrender. The President clearly stated, however, that the policy of unconditional surrender did not entail the destruction of the populations of the Axis powers but rather, “the destruction of the philosophies in those countries which are based on conquest and the subjugation of other people.”
Sorry, but your submission has been removed because we don't allow hypothetical questions. If possible, please feel free to rephrase the question so that it does not call for such speculation, and resubmit Otherwise, this sort of thing is better suited for /r/historicalwhatif.
