If Hitler doesn't occupy Bohemia; the British and French may go along with Hitler's bullying on the corridor and Danzig
Bohemia represented a shift

If Poland submitted on the issue I wonder if Hitler would have attacked them at all. He put to paper that he didn't want to and preferred a rump polish buffer state to keep germany from having a common border with russia (mid 30's hitler didn't have all the dreams of 1941 hitler)
I wonder if Germany would actually ask for the corridor - in OTL Germany only demanded Danzig and free passage across the corridor, but not the territory itself. I suppose Britain and France would still be in appeasement mode, and Poland would agree to this for lack of other options.
The interesting question is what Poland does once Hitler inevitably crosses the line and the guarantees start to roll in from London. Will Poland decide to accept them anyway, or will it conclude that since Germany currently has no demands against it, it will be best to remain neutral and wait to see what happens next. In OTL Poland hoped that the French 'threat' to Germany's western flank would discourage Hitler from attacking at all. If he demonstrates that he is completely unafraid of France, this rationale disappears and Poland probably declines Anglo/French overtures and remains neutral. (One possible way to have this happen would be if Hitler decided to leave Poland and go after Yugoslavia - the obvious place to get the plunder needed to sustain Germany's economy. Britain and France declare war, Hitler laughs in their faces and they do not react as Yugoslavia is overrun.) In the longer term, Hitler probably gets yet another ally in 1941 - which, I think, is what he originally wanted.
the Rhineland, the Sudentland, and Austria all represented the will (more or less) of the people who lived there wanting to go back to Germany.
The corridor and Danzig would have represented much the same and Poland was hardly the nicest caretaker of it's German minority.
Many Germans might consider it the same, and London and Paris probably wouldn't care. But unlike Danzig and the Sudetenland, the corridor had an overwhelming Polish majority in 1939, and I have heard little evidence of their desire to return to Germany.
