Ribbentrop was an Anglophile and had spent a lot of time in Britain. He served there as ambassador and tried to convince Hitler that Britain could be converted into an ally if allowed to keep their colonies. If Churchill had not been convinced that Roosevelt would rush to his aid, who knows what kind of “deal” they might have made.
I don’t think any “deal” between Hitler and England was in the cards. Not even close.
Maybe in 1934, but once it became clear that England would not ally with Germany around the 1936-37 timeframe, like a lover spurned, he became the biggest Anglophobe in Hitler's inner circle.
