You are right the debate nees to move a head from  its present stage.Could you do that by throwing light on how did Heidegger influence Searle's work on intentionality?Is it through Searle that Heidegger's influence passed to other American philosophers? I know that Rorty is a great fan of both.I think most of the participants in this debate recognize the divide and I think most of them agree that in most cases it does not affect intelligibility.Don't you think that it is time to discover the areas of mutual influence if there are any?
